Query: More than thought provoking

My sister-in-law recommended this film to me. It's laced with brilliant subtle dialogue and sci-fi effects, while building to a very thought-provoking climax. It's one of those films I had to watch again to get the clue-filled conversations. I have fun convincing my friends to watch it without revealing the underlying message. I recommend with whole heart.
