I love the controversy...
I really enjoyed the movie, there are definitely some flaws, but so far its the best summer movie Ive seen, I look forward to more "gap-filling" in the sequel(likely since it is approaching $300 million). Genuinely like a movie that doesn't explain everything to the audience!
With just over 100,000 ratings, Prometheus seems to be doing quite well on IMDB, with a 7.6 rating. I don't think the perception that it wasn't well received by the audience is reality.
