My top-five list:
1) Jean versus Xavier
The whole sequence was mind-blowing, from Xavier, Storm and Logan approaching Jean's house to Logan and Storm crying over Xavier's empty wheelchair. As Xavier levitates out of his wheelchair, I felt like I was rising from my seat. Magneto yelling for Jean to stop broke my heart. Juggernaut throwing Wolverine through the ceilings gave me a geekgasm. Storm rising and doing her new spinning trick towards Quill and Arclight was fun-tastic. The score was great.
2) Magneto in the convoy scene
I'd pay again to see this scene anyday. Absolutely amazing and I especially loved what Magneto did with his hands. Very creative and my mouth dropped open when he crushed the first car and then just threw it away to the side. He owns.
3) Jean demolecularizing everyone at Alcatraz
My God, I did not expect to see her going THIS crazy, killing everyone. After Beast curing Magneto and Wolverine saying that it was over, I thought it was truly over, but when the soldiers fired the cure darts at them -- it wasn't over. I was on the edge of my seat when she demolecularized the cure darts and turned to the soldiers, and then the fun began. The score was absolutely amazing and I can't stop listening to it. It's a shame that we didn't see any Phoenix flame, but it was still good. Famke Janssen definitely pulled it off. Loved the climax.
4) The Final Battle
It was freakin' awesome. Enough said. Magneto raising the debrises, shielding them from the cure darts, was unexpected. Arclight destroying them was great, too, and I was ready to hate it, but no, I loved it. I was, like, cheering Arclight for doing that. The X-Men entrance -- I felt it was completely lifted from the pages in the comics. I was totally doing my geek-dance right there in front of everyone. Beast kicked asses. Magneto kicked asses. Wolverine kicked asses. Everyone kicked asses. Finally, we got an all-out war and NOT just Wolverine fighting one-on-one fights.
5) Wolverine versus Marrow-Man
Seriously, this fight was awesome and just had to be mentioned. Loved it!
