Here are the things I liked the most:
1. Quicksilver rocked! Wish he had more to do later on.
2. The future mutants were cool, but ditto - - same as Quicksilver
3. All the cameos at the end, very nice.
What I didn't like so much:
1. Not enough Quicksilver!
2. At least they could have had some sort of montage concerning the fates of some of the FC X-Men.
3. Outside of the basic travel-back-in-time-and-inhabit-my-younger-self, this was SO far removed from the "Days of Future Past" comic that is was . . . too different.
I agree with this review - - 4 out of 5 stars is just about right. Why did Anna Paquin get top billing along with Halle Barry, Hugh Jackman, Ellen Page, etc.? I mean, if that was even her, she had, what, a 3 second cameo with no spoken lines at all? I understand her parts were edited out so it must have been some contractual thing.
