If you gamer-type anime fans were holding out hope that the game attached to the Dragonball Evolution flick (yes, of course there's a game; it's a movie. Hello?!) would turn out less horrific than the film looks these days, well...you probably shouldn't read on.
That said, Wired has shots from the game, which unfortunately decided to try and emulate the film version of the characters rather than looking remotely like the original anime/manga characters. In terms of actual gameplay it looks like pretty standard fighter fare, so it might not be awful, depending on whether you like the look of the movie. Make sure to hit Wired up for their whole collection.
UPDATE: Giant Bomb has more....if you want 'em.
