Visually, DragonBall Evolution gets the job done, but considering it's pretty much just a 2D fighter, the only thing it really needs is nice looking models and backgrounds, plus some special effects for the more powerful moves. Well, it has that. Between fights, when the game is progressing the movie's story, the stills used look like post-processed and cel-shaded versions of the actors themselves, and in-fight, the models, while not as detailed, look pretty good as well. As for the fighting arenas, the backgrounds look like many of the main locations from the movie. You will see everything from Gohan's house (both built and in rubble), to the desert where they meet Yamcha, to the temple at the end of the movie where the dragon finally gets summoned.
Sound is okay and entertaining, but it really doesn't add anything to the overall experience. The story-advancing cutscenes use text instead of voiceovers and the only real voice acting are the frequent one-liners shouted out in the game's fights. The game's background music has enough energy in it to keep you moving, but much like the rest of the sound package, the game doesn't feel all that different when you turn down the volume.
