Others have praised some of the action scenes, but I found most of them to be both staged and filmed very badly. There's a chase with the batmobile early on where it's never established where the vehicles are relative to one another, and it just cuts from showing one car or the other, but almost never in the same shot. It made the scene chaotic and difficult to follow. Lots of good individual shots are framed well and there's some good pyrotechnic displays and car/gadget designs. But the sequence is a mess.
The thug beatdown scene shown in the trailer was similar. On the one hand, it's the best sustained action sequence in the film. It's set in a mostly empty warehouse, in a couple of large, open rooms, but for some reason mostly shot up close so we can't tell who is where, when. It also used most of its good clear shots in that trailer with much of the remaining action filmed too close, camera shaking. Overall it's just fine, but in the hands of a competent director, the sequence could have been so much better. They basically had a fantastic approach to Batman's combat style, gave him a good set up, and then filmed it in a way that actually undercut how good the stuntwork was.
