I loved the movie. A lot of people I've been talking to said it wasn't as good the second time through though.
I'm going to wait another month or two and watch it again to see.
Anyway, yeah the camera work is pretty good. It kind of gives the movie a more documentary feel at points (especially in the ending sequence).
I want to say more, but I also don't want to ruin it for people whom haven't seen it yet.
