My 2nd viewing thoughts on Prometheus

Ok So I was super excited about prometheus after the insane hype and lush visual presentation of the marketing machine that surrounded it. I think Im fair to say that everyone on this site has been a little dissapointed in its delivery; if only from the fact that no film can possibly live up to the hype machine driving this one. I watched the movie twice, if for any reason to try and figure out if i liked it or not. Here is something that popped into my head after the second viewing. I get the impression that the USP of prometheus is something of a red herring. Ridleey Scott said in big bold letters that he was from "The school of big things" or something along those lines- that the film was about "everything." after a second viewing i see the point of this remark. Ridley Scott clearly wanted to make a philosophical movie about the nature of creation but was in essence confined to a structure of a sci fi horror. The one interaction of prometheus that stands out is davids actions amongst both the humans and the engineers. He manipulates the entire plot to the point that he is aware that the engineers want to destroy earth, he mentions this to shaw before awakening the alien "to create one must first destroy." This has particular reverence given his line earlier regarding weyland "Secretly doesnt every child want its parents to die." It was this, among with davids solitary scenes, that gave me the impression that ridley was trying to put more an emphasis on the relation between android and human rather than human and "engineer." In fact Id push to say that promethues has a hell of a lot more to do with blade runner than the original Alien. The Whole "Alien" aspect, in fat, falls flat in the film. Id challenge anyone to say that there was one genuinely "Scary" scene in the film. Rating fears or not, the films horror aspect was beige. To me its due to the fact that prometheus was never meant to be a sci fi horror but felt it had to be, in some respect, due to the nature of its heratige. Im warbling and not sure if im making a point but id be glad to hear thoughts on this. I will also say though since no one else mentioned is HOW FUCKING SHIT THE MUSIC WAS!!!! why has there not been a thread on this!!!
