There is but one word for this movie: fun! - X2: X-Men United Reviews

X2 is easily the most fun I've ever (EVER) had in a theater. For Marvel fanatics, or even just kids who used to watch the Saturday Morning Cartoon on Fox (like me), it doesn't get much better. My brother and I loved naming each and every hero in the school and watching the great fight scenes (especially the one of Wolverine v. Deathstrike). So much fun, anyone who knows anything about the X-Men will love it.
