Forget movie critics. There may be no more unforgiving, opinionated and passionate film audience than the one in cyberspace - the fans, the obsessives and the self-proclaimed geeks who hang out in Internet discussion forums commenting on every casting decision, every script rewrite and every shred of pre-release advertising material for movies that haven't even been made yet. 

And X-Men: The Last Stand - the third installment in the acclaimed mutant-superhero franchise, which opens May 26 - has come under closer scrutiny than most. As anyone familiar with the comic books will happily tell you, this is NOT just another X-Men movie. This is the story of the resuscitation of telepath Jean Grey (played by Famke Janssen), who died at the end of the second X-Men film, and her transformation into Dark Phoenix, a mutant so powerful she is capable of destroying entire planets.
