Eh. Both CA movies had the same problem; they start well, try to make a play for characterization, then a little ways in they say "

it" and just run a bunch of poorly-strung action scenes against a poorly-defined enemy that you don't care about at all. Hugo Weaving was completely wasted and the second movie didn't even have a real villain character.
Edit: Thinking about it now, I can't even remember the villain even though I saw it a month ago. That's how bad the second movie was.
Edit2: Just remembered. Yeah, that was a crap villain too. So pointless and obvious.
