Just got back from Batman. Of the three movies in the thread, I felt Spiderman was the best of the three. It was a fairly new take on the story, was well written, well acted, well directed, and was just an awesomely done story. And Andrew Garfield and Emma Stone are the perfect Peter and Gwen. They are perfect together with such a great chemistry they were totally believable in that role.
Avengers was the second best. Just an awesome thrillride from the outset. Good story, good acting, etc. I am just more of a fan of the origin type story. With so many characters it is hard to draw a real connection even with the four predecessor movies. Not enough screen time for all of them, but that is what that type of movies has to be and in that I can't see how they could have done it much better.
Batman felt too similar to the first two and sure they all related together, but it was way too much of a rehash of the first two for me. The three villains in the Batman movies were just out for chaos for the sake of chaos and that just doesn't resonate well with me. Liam Neeson and Heath Ledger did a great job of it, but you just didn't that connection with Tom Hardy. I did really like Catwoman in this. By far the best movie version of her.
