I actually created a similar topic last month. Here are my lengthy thoughts on the series:
I personally have mixed emotions toward the series. It was nice to see another animated Sonic show after several years, but I feel it could have been better. A lot better. And I'm not just talking about Chris. The show had plenty of other flaws.
One thing I disliked was how flanderized many of the characters became. Sonic went from being carefree to being a lazy bum for half the series. Amy went from overeager Sonic fan with a fighting spirit to a just plain psychotic Sonic fanatic. Knuckles, who actually had an air of cool about him in the first few episodes, quickly devolved into a musclebound oaf who was good for little more than comic relief.
Another thing I didn't care for was how horribly overpowered the characters were. Take episode 13, for example, when Sonic is fighting against Eggman's robot. Any normal creature would've been dead after being smacked just once by that thing. Sonic gets smacked around multiple times, is smashed into a wall, and then SOMEHOW finRAB the strength to PUSH HIMSELF FREE OF THE ROBOT'S GRIP like he was friggin' Superman or something. I can understand Sonic being resilient, but you have to draw a line somewhere. And don't get me started on how ridiculously strong Shadow was, being able to wipe out entire armadas with a wave of his hand. Sometimes I wonder if the Sonic characters could give Goku and frienRAB a run for their money.
Let's talk about the storyline. Not bad, I suppose. The first few episodes had great promise, but before long the series became rather formulaic with Eggman attacking in his (rather lame) robots. Things did start to improve after the first half of the series, though. The sad thing is, I think the best episodes were the ones that adapted the Sonic Adventure games. There were other episodes that were rather fun, such as the one when the city is attacked by Eggman's mobile fortress or when Sonic has a footrace with Sam Speed. Other episodes were insanely bad, such as the episode when Sonic can't quit running because he has a scrapped robot's chip stuck in his ear (um, what?). Or how about the one where Eggman brings household appliances to life and attacks the city with them like some lame early 90's cartoon? And don't get me started on the incredibly lame excuse for an "adaptation" of the Sonic Battle game where the city has a completely random fighting tournament to determine who gets a Chaos Emerald. There are plenty of animes that are suitable for tournament episodes. Sonic X isn't one of them. I mean, who wants to watch Sonic and co. fight in the same tournament as middle-aged maiRAB and little boys?
As for the dub...well, I suppose we really don't need to go too much into it. I did kind of enjoy the little jingle that played whenever Sonic appeared, and utterly despised how frequently Rouge's screechy saxophone theme played.
Also, I think Griffith's voice for Sonic is much better when he does it in a higher pitch like the early episodes.
One last thing that was really hit and miss was the animation. When it was good, it was spectacular. And when it was bad, well, you got rivetting fight scenes like this.
