What X-Men offers are outrageous makeup and costumes, gaudy overproduction and that bland, dopey dialogue.
This is a film that should satisfy fans of the hugely popular comic book and audiences who can't tell one uncanny X-Man from another. Mutants rule.
It's darker, more complex and far more substantive than anything in the Superman or Batman cinematic series.
New York Times:
Clumsy when it should be light on its feet, the movie takes itself even more seriously than the comic book and its fans do, which is a superheroic achievement.
Had it simply ignored or abbreviated the inescapably hackneyed origin stuff, the movie might have been in a position to break some ground.
The script could be a lot snappier, particularly during some virtually unexplained rivalry banter between Marsden and Jackman, but X-Men is a decent start to what will no doubt be an immensely profitable series of negligible but enjoyable summer movies.
Exciting mainly because anything can happen and does, the movie drags a bit as it approaches a climax set on top of the Statue of Liberty. But once there it revives.
The direction sometimes lacks vibrancy and occasionally obscures the action and special effects.
X-Men, it must be said, has only a few truly thrilling moments. This is not a picture that tries to blow you out of your seat. But more than any other big movie this summer, it has a consistently inventive vision.
The most beautiful, strange, and exciting comic-book movie since the original Batman.
New York Daily News:
The X-Men comic books have spawned a cottage industry of mutant characters, and the movie helps make sense of these legions while offering the established fan base something new to cheer.
The film is effectively paced with a good balance of exposition, character development, and special effects-enhanced action.
The events that end the movie are sort of anticlimactic, and the special effects, while energetic, are not as persuasive as they might be.
It sucks that this choppily edited film appears rushed and incoherent in ways that cheat the story of its human resonance and the stunts of their anticipated pow.
A distinctively absorbing entertainment, offering just enough popcorn thrills for mass audiences and just enough chewiness for hardcore sci-fi fans.
It's a rich, impressive comic-book fantasy.
Globe and Mail:
All these characters with their odd powers are inherently absurd and they throw a barrel of wrenches into the machinery of a coherent narrative.
Apart from the brushed metal production design and pin-sharp camerawork, this offers only moderate excitement.
X-Men plays like a so-so middle chapter of an epic series rather than a fitting kickoff.
It ain't saying much but, when it comes to stoopid fun, X-Men could be the summer movie to beat.
