I just saw it in 3D (only option available at this theater) this afternoon. I enjoyed the movie, but then, I seem to be less discerning than some folks I've seen, when it comes to movies. I'll second Billzilla's procedural comment, but it's easy to give them a pass on that (Gotta keep the story moving, don'cha know!).
Clooney was about what you'd expect. Bullock brought her "A" game. Her role was more challenging, with more room to stretch out in.
I thought the cinematography was very good, and definitely justified the expense of seeing it in the theater. That's coming from someone who doesn't catch many movies in the theater any more, (and has come to view most of what comes out of Hollywood as drivel).
