text: I must say that I wasn't impressed at all, probably because I was expecting much more from this movie. Maybe an accent on religion vs science or on the meaning of life, not just a few lines. So, if you expect something to think about after you see this movie, don't. It's more psychological than philosophical. I vote 4 because of the end, it clears up a bit and because I have a great respect for BBC documentaries. There are a couple of very interesting scenes that actually gave some sense. It was a brilliant idea to add it in a movie related to theory of evolution, too bad that this wasn't the main subject. Ah, I just forgot to say that for more than 1 hour, the movie is quite boring and in a way, cruel.
