I love Ridley Scott. He's made lots of great stuff including: Alien, Gladiator, Black Hawk Down, The Gathering Storm…. So I had high expectations for Prometheus and was let down.
I found it to be a mess. The plot was never really made any sense and there was too much jumping around without context. The acting was mediocre except for Michael Fassenbender who was awesome as the robot. Really creepy.
I give it 5 out of 10.
Roger Ebert really disagrees with me on this one:
Ridley Scott's "Prometheus" is a magnificent science-fiction film, all the more intriguing because it raises questions about the origin of human life and doesn't have the answers. It's in the classic tradition of golden age sci-fi, echoing Scott's "Alien" (1979), but creating a world of its own. I'm a pushover for material like this; it's a seamless blend of story, special effects and pitch-perfect casting, filmed in sane, effective 3-D that doesn't distract.
