I'm a huge Sonic fan so naturally, I'm going to want to buy this DVD. The animation isn't the best but it's not as bad as the "Adventures of Sonic the Hedgehog" series. The English dub isn't that good at all. I don't think Sega ever intended on having Sonic sound annoying at all. Sonic and Knuckles are NOT best friends, they're rivals. The fact that Tails is a technical genius is addressed as well as him being immature. The whole rival angle between Sonic and Knuckles does get addressed at the end of the movie making for a rather humorous ending. I did catch an adult oriented joke in the movie. The reason that I still give this 4 stars because it has a well thought out story behind it. The Japanese voices seem more natural than the English dubbed voices.
