The fact that X3 deviated from the source material doesn't make it the terrible film the fans of the comics made it out to be. To the average movie-goer (and a large number of critics) its solid summer fare. Great action, dazzling score, the most serious tone in the trilogy...Purists think that straying from the books makes for an immediate cinematic abomination. That's crap. Look at Hensleigh's Punisher film. Great film, but everyone hated it for not being a true "Punisher" movie. Again, crap. Captain America was close to its roots, but was it a great film? Not even close. This is an old argument that will never end in the comics community. "It wasn't like the original comic!!! THEY BUTCHERED IT!!!" No. I've read about what Dougherty & Harris wanted for X3 & it sounded pretty dull. Leave the cosmic entities to the Fantastic Four. The X-Men, cinematically at least, inhabit our world. The REAL world. I prefer the mother of all mutants/Class 5 angle on film a hundred times over cosmic starchild Jean Grey.
