A commercial film that's actually subtle

I imagined this was going to be one film from the previews I'd seen, but in reality it turned out to be another - a far more subtle experience than I had expected. A lot of the people in the packed theatre where I saw it apparently expected that other film too; they seemed disappointed when they'd left - they'd probably been expecting yer basic escalating violence, with us cheering for Jackson as the good guy and Affleck as the bad. Not a black and white movie (no pun intended), more of a karma sort of thing, with the two main characters learning from each other in ways they never realized they would (or needed to). And heavy-handedness is nowhere to be seen. Kudos for that alone.
