Invitation to where?

Rating: 7/10 (9 June 2012)

In the movie we can see a five star sign, which is a starmap. Or an invitation. Invitation? To a biological weapon store? The planet is a weapon store. Why they provided an invitation to a real trap? Or to a military weapon test field? The Space Jockeys were a really pervert guys.
Why the last remained Space Jockey hunts the girl? Why he did not choose an another fully operable spaceship to end the main mission? Was he a real superhuman? Or a common dumb guy on a lot of steroids? The flute startkey for a spaceship was really cool :) David said, the organism was 12 weeks old, but actually this was just a 10 hours old, but David have not seen this octopus-like organism before. How could this android decided this organism age?
