I vote TA for the same reason I voted for ROTS in the other topic. It's a complete movie where you can enjoy the story even if you haven't seen the films preceeding it. The other Marvel movies explain some things in TA, but they're not essential the way the preceeding Potters are to DH II.Aside from that, as good as DH II is, I can't think of anything great about it that doesn't come from the book. The epic story and characters that JK wrote are the reason the film is so satisying. Yate's direction is pedestrian, the acting (aside from the superb Rickman) is just ok and the score (aside from the too little re-use of Williams' theme) is unmemorable. With the Avengers, Whedon and the cast added a lot more than was in the comic. The beautifully shot action and terrific humour and character interaction elevated what could have been just a ho-hum superhero story.
