In the "not too distant future", mankind is beginning to experience the next phase of evolution. Mutations have endowed select humans with superpowers, allowing them to walk through doors, cut through steel with laser-beam eyes, or reach out and touch someone without ever dialing a phone.
But these abilities have left the "have-nots" of society concerned, leading U.S. Senator Robert Kelly (Bruce Davison) to propose legislation requiring registration of all mutants. However, Charles Xavier (Patrick Stewart), a telepathic mutant, sees education as the solution and has dedicated his life to teaching young mutants to use their powers to benefit all mankind. His students are the X-Men.
His nemesis, Magneto (Ian McKellen), who possesses the ability to bend iron with his magnetic personality, doesn't see things the same way. Instead, he creates a mutant mafia to assist in his plan to convert all humans to mutants. The most notable member of his team is the voluptuous Mystique (Rebecca Romijn-Stamos), who can change into anything -- except her clothes. Wearing only blue body paint and some glued-on scaly things, carefully positioned camera angles keep from revealing too much Mystique.
Xavier and Magneto are both interested in recruiting two "independent" mutants: Rogue (Anna Paquin), a young girl who can't prevent herself from sapping the life out of anyone who touches her, and Wolverine (Hugh Jackman). A walking Swiss Army Knife, the strong steel blades that shoot out from between his knuckles whenever he is attacked, along with an ability to heal himself, make him a formidable force.
Between Wolverine's slashes and the other paranormal powers possessed by these characters, violence is frequent and often explicit. People who stand in their way are thrown around like dolls, bleed and suffer from many strange forces, or decompose into viscous liquids. They also tend to destroy any location in which they meet.
Even though teens may find a defense with the (thankfully) relatively clean language, considering the amount of carnage these X-Men deliver (and the two planned sequels to follow), parents will want to carefully consider if they want their families to be recruited by X-Men.
