Everything about this film is opposite from everything I hate about most modern films. It's un-self-conscious, it's subtle, it doesn't rely on Liam Neeson style heroics, it has a grain/grit that you just don't see anymore, an attractive female who doesn't become romantically entangled, a plot that unfolds with minimum exposition, peripheral characters that all feel credible and unshowy. I completely forget I'm watching a film, getting immersed in the performances and atmosphere in a way that feels genuinely anxious. It's when watching a film like this that I remember just how awesome cinema can be.
I love how the story unfolds, including what some complain of as being a slow beginning. Its only slow if you're expecting an action film. It's slow in the way that The Conversation (a firm favourite) is slow - its about character, detail and atmosphere, but everything is thoughtful.
