Directed by Bryan Singer (The Usual Suspects, Apt Pupil), X-Men is an unerringly smart comic-book adaptation that plumbs its source material for real relevance and deeper meaning while still delivering all the biff-bam-pow action a comic book fan could want -- as well as serving as the launching pad that made Hugh Jackman a star with his work as the feral-but-stalwart Canadian mutant, Wolverine. Some of the dialogue is a bit laughable -- and Halle Berry, as the weather-controlling hero Storm, doesn't do much to help with that when she's on-screen -- but the effects are top-notch, the script is smart, and the tone of the film is pitch-perfect, giving us characters with unreal abilities at conflict in a very real world.
Launching a four-film franchise (with more, possibly, to come), X-Men is perhaps one of the best super-hero comic book adaptation, in part because it doesn't shy away from the big issues the comic explored, however clumsily, but instead embraces them. McKellen and Stewart are perfectly cast, and the remainder of the actors (with the exception of the seemingly-reluctant Berry) are all excellent. A super-hero film with real ambition and true talent can be very rare in Hollywood; X-Men is, alongside The Dark Knight and the first two Spider-Man films, one of the highlights in the modern exploration of the sub-genre.
