I just snuck out over lunch and watched it. Good flick.
They really do fight scenes better than any other movie(s) I've seen. I can only hope that other action movies learn these techniques--they must have slowed the camera down and had some monster rehearsals.
Compare the Borne fight scenes with Daredevil's fight scenes and it's night and day. Ben Affleck looks like he's moving in slo-motion, Matt Damon looks more like a super-hero than Affleck does and he's not even wearing the tights.
I also like the way they had Borne disappearing in crowds. It really gave you a sense of annonimity, even in big citie like Berlin, NY and Moscow.
What I didn't like was Julia Stiles in that role. First, she didn't seem old enough to be a field operative, much less a field operative contact/psychologist--I think she was miscast. Second, she never saw the screen again after Borne took her into the subway. Don't know why that bugged me, it just did. It was almost like she couldn't make a few days of shooting so they wrote her out of the movie at that point.
