Warning again - spoilers to be expected -
Well this was a movie I had been rather expecting, since I quite liked the second opus. It's too bad I stumbled upon a spoiler some time ago which was accurate for the first part of the movie and the two more important deaths.
Maybe that's why I feel a bit disappointed by the movie. For one thing, I found it was a bit too short - and that, considering its length, some parts were a tad unnecessary (for instance the shots of Mystique's prison-truck).
Then some characters get a bit shorthanded IMHO. I felt there was less time for character development as in the previous movies. It would have been nice, for instance, to learn a bit more about the background of Colossus and the Beast, as they were new to the team. And I really feel sad for Cyclope's or Rogue's fans.
Far worse IMHO is the Phoenix - from the moment she joined Magneto, Jean/Phoenix did little more than look sinister standing beside him (before trying to destroy everything in her path, as expected).
Finally, I found myself expecting more action scenes - the final battle was good, of course, but before that, there was really not much equivalent to the attack of the school in X Men 2.
On the plus side, well, for one thing, the FX, of course - I loved Iceman's turning to ice, and the Golden Gate flying (man, but in how many movies will that poor bridge have been destroyed ? ), and most of Phenix's pyrotechnics.
The final battle was quite good (loved the Beast, Storm, and Shadowcat), and I found the scene at Alkali Lake with Wolverine and Storm nicely done and rather eerie.
Oh and - am I the only one thinking that the "guy without brain activity" Xavier talks about at the beginning is the XMen equivalent of Spock's "remember me" in STII ?
Anyway - what did you guys think ?
