For the first half its a conventional thriller taking the side of the young activists as they execute their plot to blow up an environmentally damaging hydro dam. After the attempt things go a bit wrong and it becomes an observational psychological drama before a climax and then departing in a new direction. Very believable characters and place. A couple of minor issues - I don't think if you were going to do an action like that you wouldn't think through the possible consequences and be better prepared for them. Very good that the film doesn't moralise about their action, it simply raises the activists own internal moral ambiguity. In some ways the climax was a bit wrong and forced, but the ending is superb.
