I saw it last night....and for about the first 75% of the movie, I really enjoyed it....but the last quarter or so....I kept hoping for some kind of resolution or redemption that never came. I walked out of the theater disappointed. I was hoping that they could pull off a nice long series of movies because they had an awesome cast and there are SO many stories you could tell about them. (As evidenced by the TONS of X-men comics and spinoffs... LOL) But I think they pretty much ruined their chances of making any decent sequals.
(We didn't stay for the credits...so I'll be sending a PM right along...)
