I saw it Saturday night. Starts out a little slow but the action picks up and is pretty much non-stop til the end. All in all, not as good as the first, however, considering the expectation and hype it's very good. Remember too, that it's part 2 of 3.
You can just watch it and enjoy an action flick or try to understand the symmetry to our society that the film makers attempt to poke fun at.
You either get it or you don't...
