The film is, as all the critics say, emotionally involving, wrenching and all that. Acting is natural and realistic, down to the nitty-gritty. The valuable and rare thing here is that the story works against the most common plot at the movies today: the revenge plot. Here instead, revenge gets a more ambiguous and thoughtful treatment. We are accustomed to being flattered as an audience, sent home feeling good that "our" side wins in the end against the evil. In this film that stereotypical and simplistic Good vs Evil is taken apart. The revenge leaves us feeling unusually unsettled, which is a very good thing in a deeper sense.
