Wolverine faces off with his brother.
As the full title suggests, Wolverine provides the back story for Wolverine, the X-Men comics character. We learn why he has no memory of becoming Wolverine, why he's named Wolverine, and why he has those metal spikes that pop out of his hands. Comic fans already know all this, I guess, and the general viewer couldn't care less, but nevertheless, it's a pretty good tale of sibling rivalry, love found and lost, and revenge.
As you would expect from a Marvel/X-Men movie, the special effects are superb and the action is over the top. Good fun. Oh, and now we know the real cause of the Three Mile Island disaster!
Bottom line, 3 stars.
