The game has an interesting story, alright graphics, and some appealing characteristics (EX: new mutant powers). However I don't think it is worth buying. It is definetly worth renting though just to hear the story, and to see the new characters/powers. Be prepared however as the game is extremely repetetive. Your soul purpose in the game is to beat up everyone in section A, then move on to section B, beat up everyone there, and continue this until the end of the game. Challenge rooms are usually stumbled upon with no real indication of their existence. If you fail the challenge rooms you are pushed out of them with no ability to replay them in the story mode. However you can access them from the main menu, or replay them by replaying a level.
