I was not expecting a military science fiction film, as was James Cameron's Aliens. But at least I was expecting a horror movie, like Alien. And all because of that damned first trailer, and also by Ridley Scott, who said:
Quote"Of course, what i want to do is scare the living shit out of you."
That being said, my answer is yes! Prometheus was a bit boring, especially because I did not expect this sort of philosophical space opera.
Anyway I've learned to appreciate this film with the passage of time. There are some good concepts and thoughts there.
