Making a Japanese-based PR season is a very unique idea. Unfortunately, due to Saban recently buying back the franchise from Disney, the production team had only 6 months to produce this season instead of the usual 2-year production, a problem that would eventually plague its way into the franchise from this season onwards.
The plots for each episode are basically translated from the Sentai. Speaking of which, the translation sounds like it was done by google translate. It even credited Shinkenger's writer Yasuko Kobayashi in the opening credits!
Not helping BQ #2 is that the translation is so bad, that it sometimes make the lip-syncing for the villains feel off.
The suit acting was entirely backward. In the Shinken footage, the actors were bouncy and active in specific ways. In the Samurai footage, the actors were not until the Megazord cockpit, where they were bouncy and active which was not only very unnecessary, but very distracting
The occasional flashbacks in some episodes, which are only there just to consume screen time.
Jayden is an extremely unlikeable and hypocritical Red Ranger. In some episodes, he says that the Samurai team should always work together regardless of the situation, despite the fact that he barely interacts with his team and mostly tries to battle alone. To be fair, that did happen in the Sentai, but it's justified there instead of here.
Mia is an uninteresting Pink Ranger. Her bad cook joke also got really annoying, really quickly.
Kevin is an unlikable Blue Ranger.
The dialogue is very cheesy, especially the one-liners.
Antonio is a Hispanic stereotype, which is racist as his actor was not Hispanic, but rather Thai.
The rest of the Rangers are basically talking props that worship Jayden in every single sense of the word, which can get very irritating after a while, which could also possibly give the Operation Overdrive team a run for their money.
Speaking of BQ#12, in Super Samurai, when Lauren reveals that she is the true head of the Shiba Clan, the other Rangers treat her like she's invisible, and constantly mope about how much they miss Jayden.
Mentor Ji is one of the worst mentors in the franchise along with Gosei from Megaforce/Super Megaforce as not only does he not take part in combat, he also shows blatant favoritism to Jayden and gives poor advice to the team. And when Antonio tries to join the team, he not only rejects him because of his heritage, but he actually took his Morpher away, which is stealing.
The return of Bulk and the addition of Spike felt like discounted fan service without the development, especially since Skull was basically sidelined outside of a small guest spot.
Speaking of which, Bulk is really unlikable in Samurai & Super Samurai
The Bulk & Spike parts are so silly and childish and it feels like watching a bad episode of Ed, Edd n Eddy.
Some poorly written episodes, such as Broken Dreams, He Ain't Heavy Metal, He's My Brother, and The Strange Case of the Munchies.
Some moments can get very anti-climatic, one noticeable example is in the episode of Power Rangers Samurai "A Fish Out of Water", was Yamiror, the main Monster-of-The-Week, is about to spew out poisons breath on a woman holding a freaking baby, the Red Ranger comes to the rescue by.....blocking Yamiror's breath and tells the woman and the baby to go. This is one of the most anti-climactic action moments to happen in not only the Neo-Saban Era, but in the entire franchise. Plus, it's also not a bright move if you think about it as the breath could have easily passed by the Red Ranger and hit the woman and the baby.
The Samurai & RPM Team Up Episode (Clash of the Red Rangers) was one of the worst team-up episodes of the Power Rangers franchise.
Master Xandred is a very boring and unintimidating villain, who spends most of the season drinking medicine (which is actually alcohol in the Sentai).
Speaking of which, not only is he technically drinking alcohol, but his name is literally based on a type of drug brand called Xanax. Considering this show was made for a young audience, especially since this show aired on Nickelodeon, it's a rather hypocritically inappropriate reference.very
Octoroo was a really annoying villain, who keeps saying "ooh-ah-ohh" in every episode.
The Mega-Mode suits for the Megazords only exists just for toy sales. This will be even more common in Super Samurai.
The theme song, while catchy in terms of the beat (being the original 1993 theme with edited lyrics), has the rangers shouting out their names for some reason, which is unnecessary. This will be continued until Power Rangers Dino Charge.
The casual sexism. This is a holdover from the Japanese-made sentai, which don't have the same values as the western world.
Poorly-done censorship, such as Xandred's medicine, as stated above.
Some of the episodes are nonsensical, such as the episode "Trickster Treat", which is advertised as a Halloween special for Super Samurai, even though it barely has anything to do with Halloween and is more of a story-oriented episode.
Overuse of Sentai footage. Speaking of which, its' finale, "Samurai Forever", relied HEAVILY on Sentai footage.
The final episode for both seasons was a Christmas special (which in turn, was a clip show), which will be a recurring theme for later seasons except for Super Megaforce.
The airing schedule was absurd and nonsensical, with several episodes constantly airing out of order, one such example is Origins, even though it did the two-part pilot episode of the entire series, it doesn't get aired until much later on in the show. Unfortunately, this wasn't even fixed during the show's reruns on NickToons, which just goes to show just how very little Nickelodeon cares for this franchise.
Thankfully, it was fixed in the Netflix re-released of the Power Rangers Samurai series.
It started the trend of midseason summer hiatuses, which eventually result in a significant rating drop for later seasons.
It basically started the downfall of Power Rangers and it haven't recovered very well.
It started the trend of Power Rangers "Super" Seasons
Its second season, Super Samurai, despite being mediocre, is a slight improvement over it.
The ranger and villain suits are great.
As stated before, the theme song is catchy.
The Megazords look amazing.
Some likable characters, such as Emily/Yellow Samurai Ranger (XVIII), Mike/Green Samurai Ranger (XVIII), Antonio/Gold Samurai Ranger (XVIII) (despite the Hispanic stereotyping), Lauren/Red Samurai Ranger (XIX), Deker, and Serrator.
The finale and Christmas epilogue of Super Samurai (Samurai Forever and Stuck on Christmas, despite the latter being a clip show) are well written.
While he is unlikable, it's really great to see Bulk back.
