I've seen TWS several times and loved it the same each time - it holds up. It works amazingly well on mutiple levels - the actors are all fantastic, the characters are all well done, the story is cohesive and very tight, the fight scenes are some of the best I've ever seen, and there's literally no moment in the film that feels wasted or like filler. From the opening to the close it's exceptional on all levels. I was completely engrossed in that movie from beginning to end.
I'm planning on seeing DOFP at least once more in the theater, but the only way this would be a less of an easier poll for me is if it was The Winter Soldier vs. First Class, because for me, XFC still holds the crown for X-Men movies. It still has a place in my top 5 comic book movie list.
I would say DOFP will probably end up as my second favorite X-Men film, based on it continuing some of the First Class story and having most of the main First Class characters in it, maybe just edging out X2. The 70s era pulled me in.
I honestly wish we would've gotten at least one true XFC sequel FIRST (with Vaughn still at the helm), before this one, though, and hate that 10 years was skipped and so many XFC characters were written out off screen.
I'll probably get blasted for this, but I didn't care much for the apocalyptic stuff and all the mutants in the future - the only ones I really cared about were Charles, Erik and Logan. Seeing all the mutants that were new to the movies fighting was neat action-wise, but I wasn't invested in them as characters, so it didn't do anything for me.
