Re-watched it again since I saw it in theaters.
I think the first half of the movie is absolutely incredible but after the warehouse incident I'm sorry, I just think it falls flat on its ass. I don't feel the same amount of confidence in the script in the second half of the pic. The storytelling, editing, sequencing, and logic just seriously crashes and burns. The first problem, and my biggest, is Two-Face. First half of the movie develops Harvey Dent excellently. Very likable, interesting... he's going places. But when he becomes Two-Face, the movie is too busy throwing a bunch of sloppily edited and sequenced events to put much more into him. Isn't his character supposed to get even more interesting and complex after the accident and after he loses it? The movie goes from Harvey Dent Central to Two-Face (Here and There).
The cell phone stuff... I just don't know about it. I mean, it makes enough sense but the whole conflict between Fox and Wayne felt really forced, the whole sequence was shot and put together very shoddily, from the crap on the boats to Batman infiltrating a building full of SWAT guys, criminals, criminals in doctor outfits, criminals dressed as civilians-- while going back and forth between that and a bunch of cool-looking cell phone sonar shots. I think I got all that right. The action was pretty crappy, the cinematography and editing is all over the place, making it hard to follow, and it's just not that interesting. And then Batman's confrontation with Joker is highly random and unsatisfying. When they're fighting each other it abruptly cuts to some crap in one of the ferries that I didn't care about.
Then, the finale. Acting and dialogue is incredibly solid but the way Two-Face goes out is pretty boring and anti-climactic. I know I'm going to get absolutely torn asunder by these thoughts, but they're just that, my thoughts. I think overall the movie is pretty fantastic, I just don't think the second half of the movie is as well thought-out, sequenced, and edited as the first half. The ending itself is pretty solid and I like the idea behind it, makes sense, I just thought a lot of things about the last half and the climax was poorly conceived and executed.
It's a solid sequel but I think Batman Begins is much more focused and handles the character of Bruce Wayne far more carefully and respectfully and at no point did I feel that Begins lost its grip on the story or editing whereas I had some major problems with that in Dark Knight. I just don't think the writers had any idea where to take it after they blew up Rachel. Luckily it worked good enough to be acceptable but for all the BEST MOVIE OF 2008 and some of the things being tossed around about the movie, it could have delivered so much more in the second half. I'm glad I'm one of the few, if only, person(s) that was disappointed by the last 30 minutes or so.
I may sound overly cruel about it, so I do want to reiterate that the second half isn't BAD. I just think it pales in comparison to the writing and filmmaking skill on display in the first half of the film.
