I've enjoyed reading all the posts and varied opinions and thoughts about Prometheus. I think the movie is successful on many levels, in spite of the criticisms leveled. To me, it is essentially a horror movie in homage to H.P. Lovecraft; cosmic horror for the big screen (Cosmicism). I think having the engineers be humanoid in form brings a sense of terror to the viewer. They are weird and foreign, but yet familiar. I really like Alien and Aliens, but it was easier for me to watch those movies with suspended belief. Prometheus creeped me out.
