I didn't really have nearly as much trouble following the story and figuring out what certain things meant as I thought I would. Scotts main idea behind Shaw's quest, that aliens seeded our planet with their own DNA to form the building blocks of life on Earth, is nothing new. Star Trek did this 15 years ago and they weren't the first. The cool thing is this film finally seems to point the way what people have speculated for years. The aliens AKA Xenomorphs are part of a bioweapons program. It makes sense. Scott has said this film isn't a direct prequel to Alien and its not but it does seem to answer a few questions that sprang up after that film.
The things I found MORE interesting were the revelations about humanities creators and their motivations. They are malevolent. Its a departure from the usual stories like this. The impression the film gave about our existence was that we were just an experiment and in the end the Engineers may have just wanted to flush us down the toilet like a fungus grown for science class. Quite a punch in the gut compared to the idea of the "benevolent creator." Scott should have done more with that. Maybe he's saving some of that for a later film.
The big problem here is not enough happens. We kind of just get taken along on this story and most of it isn't very compelling. It just kind of happens unlike the interesting way the layers are pulled back in Alien. Most of the character suffer from the same problems we had with characters between Alien Resurrection and AVP-R: not enough development. The lead characters are more fleshed out though.
Noomi Rapice is good as Shaw. Charlize Theron plays a stereotypically icy ***** boss. I think the real standouts are Fassbender as David and Guy Pearce as Weyland. I read something yesterday that I'd never picked up on before. Ash, Bishop, Call, David. David, the mechanical boy who is always reminded that he isn't real. We've seen that before too. Star Trek. A.I. etc. but Fassbender is so good that he still makes it interesting. Weylands motivations seem very noble at first but in the end its a story we've heard since the dawn of man. He wanted to save his own ass. He wanted more time. He reminded me of Roy Batty, who goes to his "father" for more life. In fact the movie seems to "borrow" from a lot of different sources and not just Scotts own past work.
A friend pointed out that the film, particularly the ship Prometheus itself, has a very 2001 kind of feel. Sometimes it seems like Scott was trying to make his own 2001. The clean sterile look instead of the dirty humid used future of Alien (which makes sense since the technology is new). The ideas in the film about how humanity's evolution was guided by an extra terrestrial hand could also be found in a different form in 2001. Even the way the film was shot sometimes reminded me of Kubrick's style. The shots of David and Vickers walking down the hall seemed very "2001." Even Weyland reminded me of "old" Bowman.
There are parts of the movie where Ridley Scott REALLY could have delved deeper. Like Shaws "pregnancy" for one. There is a lot they could have done with that psychologically and with character moments. I felt that part was over way too fast. What happened to the guys in the cave seemed to go past without as much impact as it could have. More could have been done with the transformation of Shaws boyfriend. He could have tried to hide it for a while longer and we could have seen how horrific whats happening to him is over time. Davids obvious fascination with Shaw could have been further explored as well. I think more could have been done with the true nature of Vickers. We find out she's human but the way she grabbed David even made me wonder if she was a synthetic for a while. Scott introduces all these cool ideas but doesn't do as much with them.
I can understand wanting to leave a little mystery instead of spelling it out for the audience but I wish they had gone a little more in depth with the Engineers/Space Jockeys motivations at the end. I know some of that was left on the cutting room floor. Maybe we'll see it in the Blu Ray release.
