I really enjoyed the movie. No spoilers here, just two things I disliked about it.
First, the movie is a bit too long. Too much time is spent driving. This isn't "The Fast and the Furious." Wolverine does best what he does best, when he's on foot.
Second, they could have cut back on the swearing and the dismembering. Bad guy's dead, you don't need to see body parts flying left and right. Both lose their shock value after the first half-hour.
Other than that, I would recommend it to X-Men fans.
