It Had it all!
Sonic, Mario, wrestling references, and one of the baddest tunes to be pumped out in a sonic game. Nice variety of characters getting involved, and liked the unique ending. Solid performance, what a sprite animation should be.
Oh by the way to the last reviewer, the song playing throughout the movie was This Machine from Sonic Heroes. The ending theme was the Sonic Heroes theme. Search around for the OST, I got it, and love it. :D
