Seen it. (dont read below if you dont wanna get any of the plot ruined)
Just again, do not read anymore unless you have seen it.
Have to say, considering im a huge fan of the other two im kind of disapointed. The plot, which should of been so epic with Jean/Pheonix returning. But it wasnt. Instead the film seemed pretty tacky, with special effects used to the extreme constantly. Parts were unexplained. They killed off all the main original Xmen apart from Wolverine and Storm, or they at least made several redundant. Same old 'humans hate mutants' storyline, tried to make fresh with the fact that mutans can now be 'cured' which several main characters were.
It just seemed rediculous, all of it. Jean Gray rocks my spot though.
Oh and about the extra scene, the fucking Odeon closed the curtains half way through *i did a Pheonix impression which includes growling and holding my hands out when that happened haha* so im not quite sure what happens... but i have my ideas would like to know, so PM me
