Avengers is a total summer-popcorn-superhero-action-movie. It never gives you anything you wouldn't want to see in that kind of movie. There were a couple things that I found uneven (the opening sequence really bothered me for some reason and was hard to overlook to get into the movie quickly), but nothing that would make me dislike the movie. I definitely went in with expectations that were way too high. I think one of my major issues is that the first Avengers movie was all about bringing the team together. This one was more about planting the seeds that will tear the team apart in the upcoming Civil War. My personality, my neuroses, my issues make it so that I desperately want a happy ending for every movie, every story, ever. This movie, though it has a good resolution, it's not a happy ending. They're even building a bit of a romance, which then fizzles by the end which was a HUGE let down for me. Yes, I know I'm being unrealistic, and when you make movies like this that are part of a larger universe like Marvel has created, you need not only internal storylines, but story arcs that reach across movies. I understand it, but it made it harder for me to enjoy.
