Personally I'm in a hate-enjoy position with TDKR, the movie IMO was pretty weak compared to Batman begins and The Dark Knight, but not enough to make it a bad movie, still, there were a couple of scenes and events that just made me really hate it, and what made even more pissed is that one of them could be EASILY fixed with a little bit more attention to the acting, and that's

Talia's death, it's not the way she dies, or anything, it's the acting in that moment, it was awful, that **** of a whore of an actress seemes like a 9 years old faking a death scene, she's talking in pain and all of a sudden she lets her head hang and bang she's dead, it was just as bad as that fight between Daredevil and Elektra in the playground
ENNNNNNND OF SPOOOOOOILER
The ending wasn't to my liking either, because it failed to give closure, that could be fixed with a new movie following the "Nolan cannon", but the way it ended, it just created a bigger question and no valid answers, seemed like a TV show that got canceled in the worst moment it could end (I'm looking at you Deadwood, you got canceled in the middle of a conflict for fuck's sake!)
The Avengers on the other hand, it was a blockbuster but that's all, it was nice and fun all the way, but it didn't add no big drama nor anything. But hey, it didn't even attempt to, it just wanted to be like, surprise, the COMIC BOOKS, and that he did. So yeah, maybe the "awful" camera shots were there for a reason, to make you feel like you're watching a comic book, which is the way you should.
I know, Batman isn't shot that way because Nolan wanted a different feel, something less comic book and more "real", and it did work. What didn't work, for me, in TDKR were other things.
