Be Cool, Scooby-Doo!
A more comedic take of the adventures of the Mystery Inc gang, where the Scooby-Doo gang decide to travel in the Mystery Machine, seeking fun and adventure during what could possibly be their last summer break together. However, havoc-wreaking monsters prevent them from completing their journey.
Warning: You are not allowed to put in anything about Vyond, as it's common for fans to compare this show’s animation to Vyond.
- The redesigns are awful and look very little to nothing like their original counterparts, and instead look more like Warner Bros. Animation's bad attempt to imitate Seth MacFarlane's art style like Family Guy, American Dad!, The Cleveland Show (Season 1) or Brickleberry's art style.
- Speaking of the redesigns, they are unfitting in the Scooby-Doo franchise, as they fit more into an adult cartoon or parody.
- The characters are flanderized really badly:
- Daphne suffers the most flanderization as she's portrayed as an annoying, bumbling idiot. Not to mention she is a huge Mary-Sue.
- Fred dialed up to 11 and is stuck in his own ego even more than he was in A Pup Named Scooby-Doo and Scooby-Doo! Mystery Incorporated, where he is into traps.
- Velma, despite being the most likable, is now the person hiding in the gang's shadows and no one takes her seriously. And when she has her moments, she is a complete worshipper of technology and science with no moral depths.
- Shaggy and Scooby have become dumber and worshippers of only food; they even disobeyed Velma not to continue eating a food trap in one of the episodes.
- Pathetic and cruel attempts at comedy.
- Laughably bad dialogue.
- Mediocre animation and sub-par character movements, which is unacceptable, because even the direct-to-video Scooby-Doo movies have much better animation and character movements.
- At least the show tries to stay true to the classic mystery-solving formula unlike Shaggy & Scooby-Doo Get a Clue!.
- Despite the flanderization, Shaggy and Scooby's personalities are barely even different from their usual selves.
- Catchy theme song.
- It has some genuinely funny moments, especially how the "meddling kids" line at the end of each episode gets cleverly twisted every now and then.
- There was at least an attempt to give Daphne more of a personality beyond being the "rich, pretty damsel-in-distress who exists purely for fanservice".
- They still have well-known voice actors like Frank Welker, Grey Griffin, and Matthew Lillard returning from their original roles and they voice the characters very great.
- Velma’s new voice actor, Kate Micucci, played Velma quite nicely.
- Though Scooby-Doo's design looks weird as well, it is passable at best.
- Though Frank Welker speaks fondly of the series' writing, he said he didn't care much for its character designs, feeling they were too similar to SpongeBob SquarePants and Family Guy rather than Scooby-Doo.
- This series marks the first Scooby-Doo television series not to feature Casey Kasem, Shaggy Rogers' original voice actor, in any capacity; Kasem, who voiced Shaggy from 1969 to 2009, retired from voice acting due to declining health during the production of Mystery Incorporated (in which he portrayed Shaggy’s father) and died on June 15, 2014. Kasem's death leaves Frank Welker as the only surviving original cast member still with the franchise. It is also the first series with Kate Micucci as the voice actress for Velma Dinkley, taking over the role from Mindy Cohn.
- The writers were aware of demands for The Hex Girls to return and wanted to make it happen in Season 1, but Warner Bros. didn't like any of their proposed episode ideas, and the show was cancelled before they could come up with a good Hex Girls episode.
