I enjoyed Prometheus but the characters were disappointing. I didn't like the romance, I didn't like the subplots, and their motivations, and I disliked the line delivery.
I liked Fassbinder. His robotic acting was straightforward. I liked the aliens, and I enjoyed the prologue, the mythology and wylan.
I just didn't like the main cast. And it's such a weird thing, because Ridley does know how to get a good performance out of his actors. None were memorable. The exposition was hacky and forced, and basically it felt like the characters just spilled out the plot ("talking heads") instead of doing things.
Everything about it, from sound design, to aesthetic, to the cinematography is breathtaking. I loved what he build, but how can anyone get behind it when the characters were not better? I welcome a sequel. I hope for the best! There is more to tell here! I'm much less weary about a Prometheus 2 than a AVATAR 2, which I just think sounds like the same movie but under water.
