So I will assume that Google Images came in handy for some things!
I've only seen it once, too, so far. I of course was freaked-out because I half-expected things to jump out any second, even when nothing crazy was going on. I watched Alien and Aliens for the first time before seeing Prometheus, which did help make things make more sense to me. Not my preferred film genre, but...the movie WAS good, I will admit to that!
