It's great, but not perfect.
The game has great graphics, great combat and pretty good boss fights, but if you put a lot of heart into it it becomes way way too easy. Let me give an example: after you escape from the lab (and after you completed the game), when the guys start firing their artillery and you have to evade me and my cousin started a contest: who can "scratch" Wolverine the most. So i equipped Healing Factor, Vitality and Unstoppable each rank 2, 1 and 1 respectively (not all of them were acquired by then) and i walked into every bomb I saw, the end result: I was "alive", excluding the fact that wolverine had no more skin on him.
All in all the game is great, but replay-ability isn't it focus point, you being motivated to replay the whole game by being able to mutilate the enemies with more force and brutality.
Another great aspect of it is the fact that you can fight with other version of Wolverine, which I find very entertaining.
Too bad it's too easy so it looses some of it's flavor, because a game also needs to be a bit challenging and not that easy.
