Prometheus was... okay. It had great performances from the cast, but it's a very flawed film. The editing was weird, the storyline was crap, the aliens... Well, let's not go there. I think the visual effects saved the movie. If it weren't for that, the movie would have been bad. I'm not saying I didn't like the film. I'm saying it could have been so, SO MUCH BETTER.
P.S. – I think the most annoying aspect of the film is this: What makes you think the company won't send another spaceship to investigate the planet? They know where it is. Also, wouldn't they care if Weyland didn't come back to Earth? Wouldn't they feel concerned?
