re: Prometheus commercial: questions will be answered.

I'll try to look through that thread. I've heard mostly gripes about motives [why are they doing x] and gripes about stupidity [who the frick would do x]. Stupidity, I guess I could just deal with it because it is a movie. But the motives gripe, I just don't get it. The movie answered some xenomorph questions and raised new ones about the xenomorphs origin and humankind's origin. However, I thought the motives for all of the characters was pretty self-explanatory.
