I just watched this movie, and I thought it was fascinating. I know I'll be thinking it over the next few days because it is that kind of movie that makes you think, and it's refreshing to see those every once in a while. This movie is meant to be thought provoking, but not meant to scare you out of having children. It's a story of nature vs nurture, which to me is never tiring. To reviewer Susan Dickson and anyone like her, it doesn't show the exact act because Lynne Ramsey is a brilliant director that doesn't depend on extreme gore and violence to make a point, but all the kids with arrows in them should have been a huge clue to what Kevin did.
