This is Great!
Graphics: AWESOME
Are they 3D? They were very well made, and the lip syncing is some of the best I've ever seen.
Style: Great
While, there isn't much that's new to the sonic universe here, the different graphic style is a great addition.
Sound: Awful
The voice acting is absolutely terrible, and the voices didn't fit. The only one that really worked well was Rouge's voice. Sonic sounded like a geek that sniffs cocaine, and Shadow sounds like he has bronchitis or something. Eggman's voice was pretty good, but the evil laugh could use some work.
Violence: Terrible
The action scenes are too slow, and they aren't really good anyway.
Interactivity: Fair
It's all in the beginning.
Humor: None
Story: Awful
It basically had no story at all, it just jumped around. It would've been fantastic if everything tied together, aside from the Sonic in the desert thing.
I really liked this one, it was great. While the sound and voice could use some work, the animation more than makes up for it.
