As good as all the hype has been there doesn't seem to be anything 'new' about it. The trailer even copies the Alien tension building sound effect, what a cheek. In 1979 Star Wars ruled the Sci-Fi roost with every studio trying it's damnedest to emulate it then along came Alien and offered something different replacing lightsabers with cobbled together flame throwers and adventure with horror. Taking his ques form movies like 2001, Silent Running and Darkstar, Scott put Sci-Fi into the real world. The ship looked real, used, dirty and it's crew looked 'real', used and dirty which is where Prometheus falls flat everything about it is too good looking from the cast to the special effects.There's no way this flick take place before Alien.
Days of Future Past.
