This movie is decent, but hardly measures up to the great superhero movies Batamn and Batman Returns, or even either of the Spiderman movies.
Givent the scope of the x-men universe, I understand that the movie can only include a certain number of characters and that the storylines have to be changed considerably. I was disappointed, however, that Rogue was shown as a teenager, before she gains Miss Marvel's powers. Rogue is a character that works better as an adult than a teen. Rogue seems to be a cross between herself and characters such a Jubilee (regarding her relationship with Wolverine). Her teenagerness also doesn't allow for Gambit to appear, with their uncomfortable relationship. Anna Paquin, however, is a wonderful actress, and Hugh Jackman is superb as Wolverine. Professor X and Magneto were also excellently cast, although I wish Magneto was a bit buffer.
Halle Berry is a terrible Storm. She lacks a certain dignity intrinsic to the character.
The special effects, action sequences, and makeup are all pretty cool.
The main weakness of the movie is really its cheesy script. Perhaps if Joss Whedon's rewrite had been kept, it would have been better.
