Ok, after digesting it since the 12am showing last night here are my thoughts...
First, need to see this again, at least once more (in Imax hopefully), so much happens, especially in the latter half of the movie that you don't have time to digest what happens before something else happens, the pace of this movie is insane, I literally found myself on the edge of my seat multiple times.
Performance: We all knew Ledger was going to be amazing, but the unseen stuff that wasn't in the trailers is monumental. He is spot on with his performance and I want to see more of his character but unfortunately can't! If you haven't read "The Killing Joke," get it!! It's a very short graphic novel that ties in so much from the movie, especially the way they handle his "origin" in the movie, this novel really makes you appreciate the movie in ways otherwise you wouldn't be able to. The biggest surprise to me was Aaron Eckhart's performance. I love him as an actor but wow, he has so much more potential than I thought. Whether the credit goes to him or to the writing, or perhaps both....the evolution of his character from Harvey Dent to Two Face throughout the movie is beyond that of any movie I have ever seen. The subtle references and moments were crafted to perfection, soooo good!
Plot: As I said above, soooo much happens that this movie deserves multiple viewings. Everything was put together coherently and tastefully though, the progression of the movie makes sense. It is LONG! But there is nothing unnecessary that is put in, it just has so much going on that the length is warranted. This is a depressing movie! The ending is sad, so many parts are sad, but it is brilliant! I have not seen very many other directors take this many risks in a movie let alone a "blockbuster" movie like this but it sure as hell pays off. The ending left a bad taste in my mouth and when I left the theatre I was pissed off. But after thinking about it, digesting it, it was so brilliant and left me wanting more. I came out of this movie simultaneously wanting to see it again as well as see what happens next. Nolan does a superb job of crafting movies in this way, with Begins, the ending monologue made you say "f*** yeah, let's kick some a**, get the Joker, come on." I thought the ending of begins was the best in modern cinema, but this ending leaves you wanting just as much but in such a different way. Hard to explain, but when you see it you'll know what I mean.
It lives up to it's hype, it is so much more than a superhero movie, it is amazing on all counts: action, performances, plot, effects, writing, everything! I have never seen a movie and then wanted to watch it again the next day. I wish the weekend wasn't sold out because I would be at the theatre again today in a heartbeat! Awesome movie, see it, if you like good story and are even remotely interested in superheroes especially Batman, it is a no-brainer!
