I saw Prometheus last night. For a SciFi film it was very good -- superior to Scott's original Alien. Parts of the film seem rushed and the characters seemed implausible, but that's to be expected in the genre.

There's a subtle Salotrean theme in the film surrounding the nature of the "engineers": the film reveals that Proto-Indo-European shares root words with the alien language. Couple this with the fact that the "engineers" are huge, muscular white men, and the inescapable conclusion is that Ridley Scott intended the engineers to be Aryan Gods or other-worldly hyperboreans!
