Bart: Dad, how come they're taking The Cosby Show off the air?

Homer: Because Mr. (Bill) Cosby wanted to stop before the quality suffered.

Bart: Quality, schmality! If I had a TV show, I'd run that sucker into the ground!

Homer: Amen, boy. Amen.

Homer and Bart Simpson, from an April 30, 1992 rerun of the Simpsons episode "Three Men and a Comic Book"

The same show, but not the same as it was before :(

Seasonal rot is a phrase used for any long running show that experiences from a gradual drop in quality after several seasons, to either later becoming really bad or not as good as originally and before, even though the show can still make good episodes and stories, even if they are gone from grace, or just not make as much good episodes and make more duds/bad episodes and stories as possible.


There are many great shows now and again. However, if a show runs long enough, seasonal rot always sets in and writers should always think of the right moment to either end the show (good way or bad way) or bring it back on track while it's still good, or the show can just start a new writing team to improve the series and make everything better in the future.

Sometimes it's a temporary dip from which the series recovers by bringing in new writers (ones that either hardly know anything about the source material at all, or are very bad) or make the choice by ignoring all of the past events of the inferior or best seasons. Other times, it can be irreversible and grows with each new season at the point when the series has "jumped the shark" or lost its charm.

This can include flanderization of really lovable characters (characters becoming out of character), make a few or a heck-load of filler/bad episodes, animation changes (even though, the animation would still be good, but could also turn to the ugly), come up with really stupid and inexcusable plots, take gross-out jokes gone horribly wrong, make the characters take a step too far, make episodes that don't even try, drag on everything for far too long, overuse the unfunny/poor comedy and jokes, make up poor attempts to go in a new direction and declining production values, throw in the three strike formulas used in every episode to make it a bad episode as possible, make the characters never learn their lesson, and also make the episodes use the same story repeated every episode.

There are some ways to avoid (or end) seasonal rot. One way is to temporarily postpone the series and come up with more ideas at a slow pace, keep the show as fresh and strong as possible, or just come up with new inspirations.

Making a seasonal rot worse is if the creator of the show is still heavily involved.

Notable Offenders

  • The Simpsons (Seasons 11-12, 16-31; 1999-2001; 2004-20—became one of the longest declines for any American television series. Although these seasons are not as bad as post-Season 7 of Family Guy , the episodes are very hit and miss.)
  • Pokémon (Seasons 14-16; 2010-12—see what the problems are with Black and White by clicking on the link right there.)
  • The Fairly OddParents (Seasons 9-10; 2013-17—completely ran out of ideas altogether, filled to the brim with bad episodes, completely disregarded the continuity of the earlier seasons, episodes became way too generic and unoriginal due to them often lazily reusing plots of episodes from the aforementioned earlier seasons, and the characters themselves have all either been dumbed down to their stereotypes or demoted to extras. Aside from all that, Season 9 introduced a pointless new main character, Sparky, but due to negative reception, he was removed without explanation in Season 10, except only to be replaced with yet another new main character, Chloe Carmichael, who was even worse. The show's budget was also slashed, forcing Frederator to switch animation studios from South Korea to Canada. This saw the shift to low-quality flash animation in the last seven episodes of Season 10. Overall, the failure of these seasons as a result of executive meddling and the declining talent among the writing team, even series creator Butch Hartman himself, ended up getting the series cancelled.)
  • SpongeBob SquarePants (Seasons 6-8; 2008-12—these seasons are filled to the brim with bad episodes and constant gross out jokes that are not funny, these seasons also have characters being hit with character derailment like Patrick, and several of the episodes are unnecessarily mean-spirited, edgy, or disturbing.)
  • American Dad! (Season 11-13; 2014-16—Following Season 10, Season 11 was a short season and began the decline of American Dad! as a lot of characters such as Stan, Francine and Roger were terribly flanderized, a lot more bad episodes would occur and the show tried to be way to vulgar like Family Guy and South Park. Thankfully, since Season 14, the show got it's normal charm again.
  • Family Guy (Season 8-present; 2009-present—has been going massively downhill since Season 7's Not All Dogs Go to Heaven and have not recovered ever since due to heavy flanderizations, terrible and hurtful morals, tons of mean-spirited moments, and overuse of cutaway gags, pop culture references and gross-out humor. In addition, in a desperate and shallow ratings grab, the show killed off Brian in "Life of Brian" only to bring him back three weeks later in "Christmas Guy.")
  • The Office (Seasons 8-9; 2011-13)
  • At the Movies (2008-10—after the departures of Roger Ebert, who lost the ability to speak, and Richard Roeper, who stepped out after failed contract negotiations, they were replaced by Ben Mankiewicz and Ben Lyons. While Mankiewicz wasn't too bad, Lyons was inexperienced and very bland compared to Ebert and Roeper, as well as the late Gene Siskel. In addition, the set was changed to drop the prior balcony theming, the theme was changed, and gimmicks uncommon during the Siskel & Ebert and Ebert & Roeper days were used constantly, in addition to the prior replacement of the "Thumbs Up/Thumbs Down" system with the far less memorable "See It/Rent It/Skip It" towards the end of Ebert's run. These changes caused ratings to drop, and after one season, Mankiewicz and Lyons were replaced by Ebert fill-ins A. O. Scott and Michael Phillips; while they were much better and the theme arrangement used in the Roger Ebert & the Movies incarnation was reused, it wasn't enough, and the series ended in 2010.)
  • Fireman Sam (Season 6-present; 2008-present—after the switch to CGI beginning with Season 6, the show went completely downhill and still hasn't recovered from any of its flaws.)
  • Thomas & Friends (Seasons 9-10, 12-16, 22-24; 2005-06, 2008-12, 2018-21—Seasons 9-10 suffer from lazier writing, flanderization and loads of bad episodes. While the series saw a huge improvement in Season 11, the show went downhill again in Seasons 12-16, which suffer from repetitive and formulaic plots, loads of bad episodes and even worse flanderization of characters than in Seasons 9-10, except for The Fat Controller/Sir Topham Hatt, James, Spencer, Whiff, and a few others who haven't been flanderized. The Big World! Big Adventures! retool also suffers from unfunny humor, boring plots, uninteresting and badly written characters.)
  • Two and a Half Men (Seasons 9-12; 2011-15—following Charlie Sheen's meltdown, the series replaced him with Ashton Kutcher. This aged badly with fans of the first 8 Seasons.)
  • Oggy and the Cockroaches (Seasons 4-6; 2012-18)
  • Archer (Seasons 8-10; 2017-2019—the premise of Archer falling into a coma wasn't to well received by fans and many criticized these seasons for serving nothing but pointless filler.)
  • Barney & Friends (Seasons 3-14; 1995-2010)
  • Dora the Explorer (Seasons 3-8; 2003-19)
  • Total Drama (Total Drama All-Stars and Total DramaRama; 2014, 2018-present)
  • Dexter's Laboratory (Seasons 3-4; 2001-03—continued after Ego Trip, which sounded like a good series finale. Thankfully, the series did end with a decent/good episode, "2Geniuses 2Gether" (in production order).)
  • The Powerpuff Girls (Seasons 5-6; 2003-05—continued after the departure of creator Craig McCracken)
  • LEGO Ninjago (Seasons 7, 10, and 11; 2017-19)
  • Ed, Edd n Eddy (Seasons 5-6; 2005-08—Season 5 was okay, but Season 6 was too short since that season had only two episodes without a reason or rhyme.)
  • Johnny Bravo (Season 4; 2004—the slapstick and self-deprecation that made the show's humor the main highlight was downplayed, reducing it to just Johnny interacting with people with little to no humor being given off and all of Seasons 2 and 3 were ignored. Making things worse, the series finale, "Back On Shaq" was terrible and a huge insult to Hanna-Barbera because Huckleberry Hound was in it and used in a not-so-good manner.)
  • The Grim Adventures of Billy & Mandy (Season 5-6; 2006-07—These seasons lack the charm and cleverness of the first four seasons and the two titular characters also suffer from flanderization)
  • The Boondocks (Season 4; 2014, Season 4, the final season, was made without McGruder, and as a result, was poorly-received due to Granddad getting too much focus, a poor overarching plot, the elimination of several popular characters such as Gin Rummy, Thugnificent, and Cindy McPhearson, poor plots, the fact the season was aired out-of-order, Uncle Ruckus undergoing a crapload of Flanderization, and the plots being unfunny in general.)
  • Game of Thrones (Season 8; 2019—the overall story is a disjointed and clichéd mess. The way the season concludes various plots felt either very rushed, or were never concluded at all.)
  • Cheers (Season 11; 1992—93)
  • Danny Phantom (Season 3; 2006-07—another victim of executive meddling, mostly due to the firing of head writer, Steve Marmel, after the first episode "Eye for an Eye", as he wanted the show to become a lot more darker and edgier in this season onward. As a result, series creator Butch Hartman became more involved with the writing than he did in the first two seasons and most of the continuity and subplots from said seasons were ignored in favor of building Sam up to be Danny's love interest by the end, several characters like Danny and Vlad became inconsistently portrayed, and pacing issues within the episodes in question, even in the finale "Phantom Planet", due to Nickelodeon reducing the budget for the series. Thus, there are only 13 episodes compared to 20 in each of the first two seasons, and the series ended up being cancelled despite Hartman wanting to do more episodes.)
  • Teenage Mutant Ninja Turtles (2003, Seasons 6-7; 2006-09—Thanks to Executive Meddling, the series continued on in Season 6 with a complete change in tone as 4Kids demanded the show to be a lot more light-hearted. Season 7, while an improvement, also received criticism for the redesign and and rushed Story-line. Thankfully, Turtles Forever ended the series on a high note.)
  • Teenage Mutant Ninja Turtles (1987, Seasons 9-10; 1995-96—the series worsened in Season 9 with the removal of Shredder and Krang with replacements of both Carter and Lord Dregg. This is considered the moment when the series jumped the shark.)
  • Teen Wolf (Season 3-6; 2013-17)
  • The Promised Neverland (Season 2, 2021—a lot of chapters were skipped and the ending can be seen as quite lackluster)
  • Grojband (Season 1b; 2014-15the second half saw plenty of flanderizations of characters.)
  • Winx Club (Season 5-8; 2011-19—when being revived by Nickelodeon, fans didn't take kindly to these seasons)
  • The Price is Right (Season 18, Season 31 and audition period of 39—1989-1990, 2002-2011)
  • Looney Tunes (1933-35, 1962-69—tche Buddy era cartoons were poorly received due to blandness, and the classic era would experience a decline after William Lava took over as the music composer which would worsen once the Termite Terrace studio closed and was outsourced to DePatie-Freleng Enterprises and Warner Bros.-Seven Arts)
  • Tom and Jerry (1955-58, 1961-62—went downhill after Fred Quimby retired and worsened when series was outsourced to Rembrandt Films)
  • Saturday Night Live (Seasons 6, 11, and 20; 1980-81, 1985-86, 1994-95)
  • Who Wants to Be a Millionaire? (Seasons 7-17 of the US syndicated version and series 22—30 of the UK version; 2008-19, 2007-14)
  • Betty Boop (1934–39)
  • Popeye The Sailor (theatrical cartoons) (1949-57)
  • The Pink Panther (1978-80)
  • The Loud House (Season 5-present; 2020-present—major flanderization of characters like Lincoln and Leni Loud.)'
  • Bunk'd (Season 3–present; 2018–present—removed several characters, and replaced them with new, unnecessary characters.)
  • South Park (Season 20; 2016—the show went downhill during these seasons for various reasons, such as serialization, overuse of Trump humor, abandoned storylines in Season 20 due to Trump's victory, removing classic elements such as retiring Mr. Hankey and killing Satan, and becoming less focused on the boys in favor of Randy Marsh and Tegridy Farms in Seasons 22 and 23, despite flashes of its former brilliance showing at times. Luckily, the Pandemic and Vaccination Specials are looking to get the series back on track.)
  • The Ren & Stimpy Show (Season 3-5 and Adult Party Cartoon; 1993-96, 2003—the show went downhill in the Games Animation era (1993-1996) after John Kricfalusi got fired from Nickelodeon for infamous things in 1992 and Bob Camp replacing him in the control of the series as creative director and supervising director. Due to this, the show suffers from more restricted animation and less clever plots and writing, as well as spawning some horrible episodes.)
  • SuperMarioLogan (2016-present—after Jeffy was introduced to the series, he became one of the most overused characters and caused what was once a good web series to go downhill.)
  • Nicky, Ricky, Dicky and Dawn (Seasons 3-4; 2016-18)
  • Regular Show (Season 5-6; 2013–2015, these Seasons began to look more on relationships for Mordecai and they could get annoying at times, but these Seasons are good and have little to no bad episodes.)
  • Super Sentai (Season 11 of Showa Era; Hikari Sentai Maskman 1987-88; Season 13-14, Season 19, Season 22, Season 25, and Seasons 37-39 of Heisei Era; Kousoku Sentai Turboranger 1989-90; Chikyuu Sentai Fiveman 1990-91; Chouriki Sentai Ohranger 1995-96; Seijuu Sentai Gingaman 1998-99; Hyakujuu Sentai Gaoranger 2001-02; Zyuden Sentai Kyoryuger 2013-14; Ressha Sentai ToQger 2014-15; Shuriken Sentai Ninninger 2015-16)
  • Star vs. the Forces of Evil (Season 3-4; 2017-19—the show started to focus too much on the romance drama, the fantastical racism against monsters in Mewni became the series’ new main plot just suddenly, a bit right after Toffee’s death, without building up too much from the previous two seasons, and each episode had too many writers working on it, result few both old and new ideas becoming cut and mostly never used again, as pre-established in the first two seasons, as a result.)
  • Postman Pat (Special Delivery Service; 2008-17—It was generally not as well-received as the original series due to the fact it carries out most of the same flaws that Seasons 3-5 had, it has a poor mix of source material much to the repetitive formulaic storytelling, a lack of slice of life feel and calmer pacing, Pat being forced away from his postal route in Greendale to deliver every parcel to other places that are called some "special delivery", and the series itself being turned into a TV advertisement just to cash in on a popular British TV show.)
  • Voltron: Legendary Defender (Seasons 7, 8, and 18; 2018—Seasons 7 and 8 were not well-received by audiences mainly due to Shiro's boyfriend, Adam getting killed off in season 7. It wasn't even a dignified death, he died to prove how inferior earth tech is compared to the Galra.)
  • Sesame Street (Seasons 33-37; 2002-06—in 2002, the show dropped its original format, though it would return in Season 38.)
  • Doug (Seasons 5-7; 1996-99—Tom McHugh as Doug didn't live up to Billy West's performance; there were also pointless changes such as Honker Burger being replaced with a cheap French restaurant called Chez Honque and the Beets disbanding.)
  • Jimmy Two-Shoes (Season 2; 2010-11—the second season suffers from a downgrade in animation quality, due to switching from Toon Boom Harmony to Flash animation. Many also feel that the show lost its original black comedy charm and poorly handled its characters. That said, Season 2 is still said to have its perks, namely the new intro and theme song.)
  • The Wubbulous World of Dr. Seuss (Season 2; 1998—as a response to a focus group thinking the show was somewhat for much younger kids in its first season, some viewers complaining about how scary the first season was, and to compete with Bear in the Big Blue House, the show moved to Nick Jr. in 1998, dropped its storybook-esque anthology format, and shifted to only aiming at preschoolers/younger audiences instead of families/older audiences like most Dr. Seuss books. Sue Snue was removed from the show, with Sarah Hall Small replacing her. They also removed other supporting/minor characters from Season 1 like Thidwick the Big-Hearted Moose, Eliza Jane, and Mayor Stovepipe. Yertle the Turtle and the Grinch were no longer as evil as their book counterparts. The former no longer even tried to be king and take over the Wubbulous World. Terrence McBird was introduced to the cast, he constantly whined in every episode, and the plot where the Cat in the Hat and the Little Cats tried to make him like something he refused to try was reused over and over again. Some characters were flanderized, especially the Cat in the Hat; he was initially was very much like his book counterpart—even occasionally reprising his role as a trickster, as seen in episodes like "The Simplifier" and "Yertle the King"—but his snarky persona was removed in Season 2 and he became a kind, nurturing host like Big Bird from Sesame Street or Bear. His voice also changed. Furthermore, he and the Little Cats took over the show by having their screen time increase to near-Elmo levels.)
  • Naruto (Seasons 4-5; 2005-07)
  • Naruto Shippuden (Seasons 3, 5, 9, 13-14, 16, 19, 20—these seasons are riddled with filler episodes like the last two seasons of the original series)
  • The Twisted Tales of Felix the Cat (Season 2; 1996-97)
  • Dragon Ball Z (Seasons 7-9; 1993-96)
  • The Real Ghostbusters (Season 4-7; 1988-91)
  • Woody Woodpecker (1955–72—the animation became cheaper and Woody himself was toned down into a more generic hero)
  • Happy Days (Hollywood Part 3-Fonzie's Spots; 1977-84—trope namer.)


These are the ones that aren't that bad enough to deserve a page here.

  • Family Guy (Season 6-7; 2007-2009; While there were stinkers, they are generally considered the last two good seasons, especially Season 6, before all hell broke loose starting in Season 8. There are some bad episodes such as "Not All Dogs Go To Heaven", which was considered a jump the shark moment. (Despite being from Season 7, some fans tend to see that this made the decline even more notable than before.)
  • The Fairly OddParents (Seasons 6-8; 2008-12; while there were stinkers, they are generally considered the last three good seasons, especially Season 6, before all hell broke loose starting in Season 9 until the show's cancellation.)
  • Family Matters (Season 9, 1997-98—the show went downhill in quality when it was moved to CBS)
  • Yo-Kai Watch (Seasons 2-3; 2015-18—these seasons are responsible for the decline in viewership of the show, with the increase of Toilet Humor, the derailment of several popular Yo-Kai from the games, Flanderization of several characters, and replacing the entire English voice cast due to budget issues.)
  • The Big Bang Theory (Season 4-12; 2010-19)
  • King of the Hill (Season 9-13; 2004-10—The general consensus to the show's decline is pointed to Season 9 when they introduced Lucky. Many cite his introduction as the beginning of the shows decline.)
  • Futurama (Season 6–7; 2010–2013-These seasons were mostly not as well received as the original 1999-2003 run due to flanderization of some characters, the occasional bad episode and continuity errors, however these seasons aren’t too bad and they do have great episodes such as "The Late Philip J. Fry", "The Prisoner of Benda", "Game of Tones" and "Meanwhile".)
  • Thomas & Friends (Seasons 8, 11, 21; 2004, 2007-08, 2017—Season 8 introduced a retool for the series after Britt Allcroft, David Mitton, Mike O'Donnell, Junior Campbell, and Phil Fehrle left after Season 7, and HiT bought out the show in 2002. Although Seasons 8 isn't too bad, it has their share of problems, such as inconsistencies, and minor flanderization of some characters. Season 11 had similar problems to Season 8. Season 21, while not a bad season, is home to the infamously controversial “A Shed for Edward” episode, which is considered to be the beginning of the third downfall of Thomas & Friends. Though nowhere near as bad as Seasons 9-10 and 12-16, these mostly depend on the episode. There are also inaccuracies and some bad episodes here and there like "Emily's Adventure".)
  • Rick and Morty (Season 3, 2017—a lot of the writing was not as simple as it once was, but Season 4 did improve the series.)
  • Family Feud (1992-06)
  • Wheel of Fortune (Season 21-37 of the syndicated version; 2003-20)
  • Doctor Who (Season 22-24 of the classic series; 1985-87 and seasons 6-8 and 10-present of the relaunch series; 2011-14, 2017-present)
  • The Amazing World of Gumball (Season 5-6; 2016–19—It went downhill a bit in Seasons 5 and 6 as it tries to be hip and cool with the kids, and some episodes have confusing plots. But these seasons are not bad enough to have a page.)
  • Danger Mouse (2015) (Season 2; 2017-19)
  • South Park (Seasons 12-19; 2008-15)
  • SuperMarioLogan (2013-2015; the show suffered a small decline due to Bowser Junior becoming the most overused character, some weak episodes, and many of the older characters not getting the spotlight, it is known as the "Junior Era" by fans. However, many fans of SML started to appreciate this era in recent years.)
  • Talking Tom & Friends (Season 4-present; 2019-present—While the show took a slight quality drop, Seasons 4-5 are still considered to be good seasons and the new character designs are decent.)
  • Jeopardy! (Season 18-present; 2001-present—the Clue Crew made their debut in Season 18; when the five-game cap was removed in Season 20, Ken Jennings' winning streak lasted till the next season)
  • The Fresh Prince of Bel-Air (Season 6; 1995-96—the show was beginning to run out of ideas as the show was ending production soon, but this season is still good and has good episodes like the series finale.)
  • Teenage Mutant Ninja Turtles (2012, Season 5; 2017—this season is good and has good episodes like Wanted: "Bebop and Rocksteady", "When Worlds Collide" and "Yojimbo," but it felt unnecessary. The Season 4 finale could've been the series finale.)
  • Teenage Mutant Ninja Turtles (1987, Season 8; 1994—the Season attempted to be very edgy and dark like the 2003 series, while the show began to go downhill, it was not as bad as how Seasons 9 and 10 were.
  • Gladiators (Series 5-7; 1996-98)
  • GamesMaster (Series 5-7; 1995-98—the show became less about video-games and more of a sketch show for host Dominik Diamond and his friends.)
  • The Loud House (Season 4; 2019-20—there were a few character flanderizations and some stinkers, but are not as bad as what was to be downgraded after this season.)
  • SpongeBob SquarePants (Seasons 4-5; 2005-09—A number of fans agree that this is when the series started to go downhill. However, these seasons are still considered good, despite some inconsistencies with the characters' personalities and a few bad episodes, like "To Love a Patty" and "Atlantis SquarePantis")
  • Angry Birds Toons (Seasons 2-3; 2014-16)
  • The Simpsons (Seasons 9-10, 13-15, 32-present; 1997-99, 2001-04, 2020-present–Many fans mark the infamous episode "The Principal and the Pauper" as when The Simpsons started to go downhill. However despite this episode, these seasons are still good and many fans still consider these seasons part of the "Golden Age" for the show. Seasons 13-15 and 32 received mixed-to-positive reception and while average, these seasons are still considered to be not as good as the first ten seasons.)
  • Saturday Night Live (Seasons 28, 30, 33, 35, 38, 39, and 44-present; 2002-03, 2004-05, 2007-08, 2009-10, 2012-13, 2013-14, 2019-present)
  • Pokémon (Seasons 20-22; 2016-19—Sun and Moon was not at all that bad enough to deserve a page here to begin with, even if reception on the Sun and Moon run was divisive among fans and even if it had a more laid back slice-of-life tone (which slice-of-life has been common since the show's beginning), it's still watchable. However, Sun and Moon gained critical praise over the years since its release in 2016. Especially when Sun and Moon was the same era Ash finally won a regional champion league after 22 years of failure to win, and met Brock and Misty again after Brock parted ways from Ash after Season 13 in the Season 20 two part arc finale, and again in Season 22.)
  • Turma da Mônica (Season 6-present; 2009-present)
  • Rugrats (Seasons 6-9; 1999-2004)
  • Blue's Clues (Seasons 5-6; 2002-06)
  • The Angry Beavers (Season 4; 2000-01)
  • Sesame Street (Seasons 30-32, 40-present; 1998-2001, 2009-present—Elmo's World debuted in Season 30, though it would cease production in 2008 and was removed in 2012. Starting in Season 40, the show was modeled after preschool blocks like Nick Jr. and Qubo, with Murray Monster as the host. Beginning in Season 46, the show moved to HBO, was shortened to a half-hour, dropped much of its longtime veterans, and brought Elmo's World back.)
  • ChuckleVision (Series 18-21; 2006-09—the show began to lose steam during the final four series with phoned-in acting and insane, nonsensical scenarios)
  • Adventure Time (Season 5b-6 and Seasons 9-10; 2013-15, 2017-18—many fans believe these seasons have occasional misfires, several filler episodes, and rushed plot points like Jake's shape-shifting arc, but these seasons are still considered good, the finale was very well-received and Seasons 7-8 are considered a return to form)
  • My Little Pony: Friendship Is Magic (Seasons 8-9; 2018-19—in the last two seasons, the Young Six is more focused on than the Mane Six, the School of Friendship is introduced, and the ninth season in particular is controversial)
  • Arthur (Season 16-present; 2012-present—the show changed production houses to 9 Story and then to Oasis Animation, became more cheaply animated, and introduced Ladonna. Arthur was also flanderized, going from an average kid with an active imagination to a super serious character with almost no personality. Barely any episodes focus on him now because of this, and when they do, he often acts even more out-of-character. He is now often used as a voice of reason for his friends.)
  • All Grown Up! (Seasons 3-5; 2005-08—while the show itself is pretty divisive to begin with, some fans it has say that it declined after only one season due to more drama and less comedy, an art shift, flanderization, and more unrealistic plots)
  • Monster Rancher (Season 3; 2001—this season is significantly lighter-hearted than the rest of the series, with wackier villains, no real stakes until the end, a fair amount of filler, and a rushed (if still epic) climax. It doesn't help that some popular characters are reduced to one-episode appearances and Holly becomes mostly useless. It definitely still has a lot of fans though, with many saying that while the overall story is weaker the season still contains some of the best episodes in the whole anime and gave the series a more satisfying conclusion.)
  • The Flintstones (Season 6; 1965-66—the Addition of The Great Gazoo is often cited as the series jumping the shark, but Season 6 isn't awful and has some good episodes, but it was a downgrade to the series.)
  • Dragon Tales (Season 3; 2005)
  • KaBlam! (Seasons 3-4; 1998-2000—Sniz & Fondue ceased production and was replaced with more one-off shorts, though the remaining shorts were still good)
  • Cyberchase (Season 9-present; 2013-present)
  • Postman Pat (original series; Seasons 3-5; 2004-06—these seasons didn't have as much of a relaxing and calming feel like the first two seasons had, they focused way more on the kid characters and some of the main characters were cut entirely, some of the flaws that these seasons had would later be carried over to "Special Delivery Service". Despite the flaws, these seasons are still quite decent and are no where near as bad as "Special Delivery Service").
  • STIX (Seasons 1-2; 2014-2015)
  • Aqua Teen Hunger Force (Seasons 5-6; 2008-09)
  • Sailor Moon (SuperS and Sailor Stars; 1995-97these seasons are usually regarded as some the weakest of the series even though they have some of the best animation. In addition to leaving out the highly popular Outer Guardians introduced in the previous seasons, they consist of mostly comedic filler episodes and deviate from the manga's corresponding, dramatic "Dream" arc. It also doesn't help that they spends much more time on Chibiusa than on their main heroine. The final season also leaves out vast chunks of the manga compared to previous seasons, and many, many manga characters do not appear at all in the Stars anime. The fact that the Outer Guardians returned only to be demoted to extra didn't help.)
  • VeggieTales (2010-15; around the early 2010s, the animation budget was cut in half thanks to Big Idea being purchased by DreamWorks and outsourcing the animation to cheaper studios. Many episodes' plots were also rehashed from previous episodes. The revival series VeggieTales in the House and VeggieTales in the City didn't help matters.)
  • The Venture Bros. (Season 5; 2013—While still good, this season was considered disappointing by some fans. It was a short season so the show wasn't really given a chance to flesh out some of the plot points. The show is praised for massive changes and character development, while this season undid some of that and made certain things go back where they started.)
  • The Wild Thornberrys (Seasons 4-5; 2001-04—these seasons focus less on animals and locales than the first three, especially with "Eliza Unplugged", the final episode of the series, revolving around Eliza's crush.)
  • Steven Universe (Season 4; 2016-17—there is more focus on the human characters than the Crystal Gems. Fortunately, the season's second half had managed to regain fans' interest by returning to the main plot and placing the focus back on the central cast.)
  • Phineas and Ferb (Seasons 3-4; 2011-15—while still going good, but throughout these seasons, there was more emphasis on the plot formula and redundant jokes as opposed to the show's first two seasons, which had a slice-of-life feel to them)
  • Animaniacs (1993; Seasons 3-5; 1995-98—the writing took a nosedive and so did the animation, which went to weaker studios for the most part. TMS Entertainment and StarToons weren't being used at all, and Wang Film Productions was beginning to weaken in quality. The show also lost Pinky and the Brain, later controversially retooled into Pinky, Elmyra & the Brain, due to it being spun off into a standalone series.)
  • Bear in the Big Blue House (Season 4; 2002-06—although the show was still great, it focused more on Woodland Valley than the Big Blue House in its final season)
  • Drawn Together (Season 3; 2006-07—the show became too dark for its own good and constantly gave Captain Hero screen time, although this trend had started since the middle of Season 2.)
  • The Jetsons (Seasons 2-3; 1985-87—introduced Orbity)
  • One Punch Man (Season 2; April-June 2019-the animation quality dipped a little in quality but however, Madhouse left and J.C.Staff handed it)
  • Hey Arnold! (Seasons 4-5; 1999-2004)

Since seasons 8-11 and 22-24 of Thomas are considered mixed bags, shouldn't they be moved to the minor section of this article?

I'm not sure. Even if they were, in my opinion they are not as bad as Seasons 12-16, Magical Birthday Wishes, the worst episodes of Seasons 8-11, or even All Engines Go! (which I dare advise you not to call it Season 25-onwards; I'm sorry that sounded forceful to you, but I do have a point why AEG is a reboot and not a "new patch of seasons" for the show).

I don't think 22-24 is considered a mixed bag anymore, in fact, it's considered worse than seasons 12-16 by a lot of fans.

American Dad, Regular Show, Futurama, and Gumball never went downhill.

Also, Archer Season 8 and 9 were not well received and should be on Seasonal Rot, same with the TMNT 1987 Season 9 and 10.

Some other shows that went into seasonal rot: Akazukin ChaCha (season 3, OVA; 1995-1996): Some fans tend to say that season 3 was boring, & stale. The OVA also has that same reaction, though they say that it was less stale. Personally, I thought they were still really good, especially considering that... Crtl+Alt+Del: The Animated Series(season 2, 2000s): THIS got a season 2... as if season 1 wasn't awful enough. Now scenes drag on for near eternity, & the animation is EVEN WORSE. M.A.S.K. (season 2, 1986): So apparently the plot took a 90 degree turn in that season, now becoming the predecessor to the Fast And Furious film series. How lovely. Breadwinners (season 2, 2014?): Another bad show that got worse. Woopee freakin' do. The Promised Neverland (season 2, who cares): Mother's Basement did an entire video on this season.

Mighty Max (season 2, 1993-1994): Well, this one is more so a case of a good too many filler episodes, & a lackluster ending. Still good episodes, but I mean would you try to make it a more coherent story-driven show like the 1st season? Though in this one's defense, it didn't suffer as much as Akazukin ChaCha did.

For notable offenders, I would’ve like to see someone add season 6 of Totally Spies. Reasons is because, it actively retconned the continuity as it pleases and Barney actually didn’t start going through seasonal rot until season 7.

For minor example, I would add Miraculous Ladybug season 2 current because while those seasons did feature several stinkers (like season 3 restoring some things to back to status quo but not all of it) and began chunking out low-quality animation like DQ, there will still a lot of good points about these seasons such as; Marinette and Adrien learning to stand up, side characters like Alix, Nathaniel, Kagami, etc. getting increased amount of screentime, Master Fu’s background, Marinette telling Alya she’s really Ladybug, etc. and this is where the show began to focus extremely heavily on continuity. So they definitely are not too bad as most fans claim it to be.

Another notable minor seasonal rot example would be the fourth season of Winx Club. While the season did suffer several problems (coloring style, specialist drama, Riven being a jerkass, choosing to kill off an Ensemble Dark Horse in episode 102, Mitzi’s plot as a dark fairy ending too quick, the finale, plot holes, etc.), it was still a good season because we got to meet Roxy, the general tone was as good as seasons 1-3, we were given more cool Ensemble Dark Horses (Wizards of the Black Circle, the five Earth fairies - Morgana, Diana, Aurora, Nebula, and Sibylla, Andy, etc.), we didn’t have the Trix (though they did appear in the comics), we got beautiful civilian outfits for the six Winx girls, and the finale itself was alright, it could’ve been handled better if the battle between the fairies and the Wizards of the Black Circle didn’t end too quickly. It also helps that this was the last season to be dubbed by Cinelume, some episodes did flashbacks to the previous seasons (notable example is in episode 103 where they showed some flashbacks to season 3), it was the last season to be broadcasted in 4:3 aspect ratio, and it was the last time Italy produced the season first. It is not bad enough to deserve it’s own page.
