... nobody's character was black and white. People who you figure early on are dicks end up having a noble streak and the ones you think are good have skeletons in the closet and a serious chip on their shoulders. This made the movie consistently surprising (at least compared to the usual cut-and-dried action movies out there).
The movie's been out for almost 10 years now but I only just saw it for the first time (I'm now dating a woman who is into the series and I want to watch the 4th movie with her soon so I'm catching up!)
Definitely worth a watch if you like action movies with flawed, three-dimensional characters and no particular morality lesson.
