A terrible cartoon show. One of the worst cartoons of all time.
7 June 2011 | by (U.S.A.) – See all my reviews

The first Sonic show was just in the middle. Not that bad, but not that great. The second one was amazing, but was sadly canceled before the plots could be resolved. The third one was bad, but not the worst ever. But the fourth, and so far final Sonic cartoon, an anime called "Sonic X" is just terrible. Now before you say that I've never given the show a chance, I'll have you know I watched nearly every episode. And almost every single one was painful to sit through.

The first episode started out pretty good. It had a cool action scene, and did a good job explaining why Sonic and friends are on Earth in the Sonic Adventure games. The voice acting was terrible though, but it was a decent way to start off the series. But when Chris Thorndyke was introduced, the show went downhill from there. Chris is an annoying, spot-light-hogging, Sonic-obsessed, cry-baby, rich 12-year-old boy who is voiced by Veronica Taylor, who also voiced Ash Ketchum in the early seasons of "Pokemon". Chris keeps Sonic as his little pet and cries whenever Sonic leaves for something important. Here is a list of things wrong with this show, excluding Chris since I already mentioned him:

-Bland writing. The SatAM sonic series had great writing, but this show's writing is either boring, stupid, or rushed. Almost every episode is extremely predictable. For example: Chris, Tails, or Amy gets kidnapped by Robotnik, he makes this really big, really powerful robot, Sonic beats it in a few seconds and saves Chris, Tails, or Amy. Also there's the really stupid filler episodes, the badly executed remakes of "Sonic Adventure"; "Sonic Adventure 2" and "Sonic Battle", and the lame, outer-space episodes of season 3.

  • Horrible voice acting. These voice performances are worse than the

ones in the Sonic movie from 1999. Sonic sounds bored and emotionless; Knuckles sounds too loud and gravely; Tails sounds like a little girl; Robotnik sounds nothing like the menacing, evil and threatening Doctor he was in the SatAM show; Rouge sounds like she's in her 50s; Amy sounds even more obnoxious and irritating than she does in the games; and new characters like Bokkun, Decoe and Bocoe have really annoying voices. And sadly these guys started voicing the characters on the games in 2005, but luckily were fired in 2010.

  • That annoying theme song. Some people will say it was cool or catchy,

but it was really just annoying. It was fast-paced, obnoxious, and just plain stupid. Sonic SatAM had a good theme song, this show didn't.

  • Too many humans. I know I already mentioned Chris, but there's more

than him. there's his grandpa Chuck, who is a complete rip-off of Sonic's uncle Chuck. His butler, his parents, his maid. Chris shouldn't have been the main character. This is "Sonic X", not "Chris X".

  • Out of character. Too many characters just aren't their-selves. Sonic

is lazy and sleeps all the time; Robotnik (or "Eggman" as he is called in this show and the recent Sonic games) is just a big goof-ball who hates Sonic. He practically is the same way he was in Adventures of Sonic; Amy is her old self only for some reason they make it where Sonic actually likes her, which is way out of his character, since he just thought she was annoying in the games.

Overall this show sucks. It is definitely one of the top 15 worst animated TV shows of all time. Sonic SatAM is an actually good Sonic cartoon. I suggest watching that over this pile of crap.

Rating: 2/10 "Terrible"
