i liked this film a lot. it's dark, it's not a bullet-dodging, car-chasing numb your brain action movie. a lot of the characters backgrounds and motivations are kinda vague, leaving the viewer to come to their own conclusions. it's nice to see a movie where the director allows the viewer to make up their own minds.
in the end, motivated by love or vengeance, or a desire to repent - he does what he feels is "right". 'will god ever forgive us for what we've done?' - it's not a question mortal men can answer - so he does what he feels he has to do, what he's good at, what he's been trained to do.
denzel washington is a great actor - i honestly can't think of one bad movie he's done - and he's got a great supporting cast. i would thoroughly recommend this movie to anyone.
