Prometheus isn't one of those movies you should go in blind, but I do feel like overexplaining it could deprive you of the confusion and the thought provocation it gave me. And I'm sure the thoughts it would provoke will be different for all. First, Noomi Rapace and her fellow archaeologists discover a connection between various other sites that lead them to explore outerspace, specifically looking for a particular planet. A really rich businessman funds this endeavor and puts Charlize Theron in charge of the 2-year mission to get there. There are also a few other scientists and the ship's captain Idris Elba. While they all sleep the 2 years away, David (Michael Fassbender), an android with unclear motivations or intentions, has been keeping an eye on the ship. Watching David prepare for their arrival by amusing himself with basketball and movies, the tone is set for just about anything to happen. After everyone else wakes up, we're introduced to lots of characters that have to try to make us care a little bit about as you KNOW that not all of them are going to survive.
Noomi Rapace is an extremely worthy successor to Sigourney Weaver's "Ripley" taking bad-ass to a different place. Watching her attempt to fulfill one dream while losing another made me actually care about whether or not she survives. Charlize Theron, on the other hand, she's chewing the scenery and overacting so well that you can't wait to find out how or if she's going to die - the reward on that one is worth waiting for. But the character that really steals the show is David. Michael Fassbender is obsequious, sucking up to all the humans, which is a weird trait to see in an android as you'd think he wouldn't care what they think. But his delivery of the lines agreeing to make a drink for Theron assures you that he's got motivations that no other android should have.
