X:Men Wolverine is actually one of the worst movies I've ever seen.
Even with a very talented director and excellent cast, I think it would be extremely hard to make a decent adaptation of such an epic and wonderful book. With Gavin Hood as the director, I'm not even going to waste my time, and ruin the wonderful memories I have of the books.
The problem with movies is that they visualize and solidify characters that we've already created in our minds. If the movie's portrayal of the characters don't do them justice, it will extremely hard to forget the new image.
