This is a fairly short film that has a big plot, which is what is it's problem. The plot is that Jean Grey (Janssen) is back, but she can't conrtol her evil side. She goes with Magneto (McKellen) and is the most powerful mutant. Meanwhile, people have found a cure for mutants, and Magneto and his bunch rally against it, but Rogue (Paquin) feels its the only way for her to have a normal relationship. The actual action doesn't kick in until about an hour in, but it shouldn't displease X-Men fans. If you watch past the end credits, you should realise that a sequel could easily happen, though at the end, two of our X-Men are dead (again some will say three, but watch after the end credits). So, in conclusion I do recommend this, for the good action scenes, some funny lines and good special effects.
My rating: B. 98 mins. (Not counting credits) rated PG-13 for strong violence, sexual content and some language.
