If you're rating this a one star because its "boring" or "made no sense" you're just a crybaby. This was an excellent movie and it had me hanging on the edge of my seat waiting to see what was next. I didn't guess anything that happened because there were so many twists but not enough to make it repetitive. Also to anybody who didn't understand the chimpanzee part the connection was that Ricky (the Jupiter guy) had already seen that you can't tame a wild animal for entertainment and that animals are unpredictable and yet he still tried to do it with the alien and everybody suffered because of it. Overall this was a great movie
