What would you say the purpose was? This isn't intended as a contentious question;
Not at all. I only saw
The Dark Knight once back in July, so I'm really referring the most to
Batman Begins.
I suppose to summarise at the beginning, whereas in Michael Bay films you can't fully see whats going on, thats because he's misguided. He thinks fast-cutting and rapid camera movements make the action scene more exciting and intense, when in fact it is just frustrating for the reasons you mentioned. However, with Christopher Nolan not being fully able to see whats going on is actually the point and there is a good, well though out reason behind it, whether you agree with that reason or not.
Christopher Nolan said that reason was to make the audience feel like the criminals Batman is ambushing. They're confused, disoriented, lost, panicking etc. Batman's greatest weapon against them is fear. He's incredibly fast, and is master of using his surroundings and is able to appear from and disappear into the shadows in a second.
These are very modern, urban films, and I think that this style lends an intensity and grittiness that is very appropriate. The films manage to be slick at the same time too, though.
I have to say I also prefer fight scenes with classical framing. Wide shots where the audience does there own editing, as Spielberg would say, and which is prominent in the Indiana Jones films. That said, I feel that that style would not be appropriate at all for the kind of Batman Christopher Nolan is trying to create.
