This movie is basically a very thoughtful and provocative essay on the dangers of technology outpacing societal mores and the legal system. There are no real antagonist, except perhaps the protagonist himself. I was immersed and captivated by the story despite the slow pacing, The only downside for the film is the message that it delivers -- that the future is for our children and grandchildren, and not for us.I am not saying that this message is wrong, but only that it is a depressing one to contemplate if it is right.
