I also really enjoyed Prometheus despite reading plenty of negative things beforehand. I'm not really sure what's going on. Perhaps the film marketed itself all wrong, maybe it would have gone down better with audiences and critics had it not announced itself as a sort of prequel. There were things I didn't fully understand after initial viewing but just reading about all of the different theories on IMDB is fascinating.
What did you think of the score? I've heard plenty of people say it wasn't suitable.
