I wanted to love Prometheus. Really, I did, because I love Alien and Aliens so much. And Prometheus is big and beautiful (I didn't see it in 3D, just regular 2D on my home television), and with a great cast: Noomi Rapace, Charlize Theron, Michael Fassbender, Idris Elba, Guy Pearce, etc. But I thought it was slow, and not in a creepy, tense way, and not scary, and I was underwhelmed by the aliens. I didn't really care about any of the characters because the movie took more time being slow and beautiful and didn't spend any time with the people so you could get to know them before they got killed off. Beautiful, yes, but boring - and an Alien movie should NOT be boring.
Also, what the hell sort of biologist would look at that rearing, hissing, alien snake thing and want to cuddle it? What a moron. It's an angry alien cobra, for chrissakes. I kind of had a hard time taking the rest of the movie seriously after that.
