Where to go from Prometheus

I discovered this forum after I was thinking about the film Prometheus. I had heard that the film was said to have plot-holes. I didn't notice any. It is a brilliant filmmaker that is bold enough to leave some questions unanswered, it takes a level of confidence, and a great deal of skill to anticipate what the audience wants, and to court that relationship without asking to much, Prometheus walks the line carefully. Early on Prometheus speaks to our human condition, featuring characters that are believably flawed, while contrasting those characters to a robot that emulates humanity. Wayland is successful phalic narcissist who has nothing to lose. He has a god complex. Wayland has actually recreated humanity in the image of his choosing, and he denies the completeness of that creation with a claim that cannot be substantiated. (David has no soul) What would a person like Wayland do while contemplating death. How many people around him are delighted to see him dead. Can a god die? Could an uprising of synthetic's occur? What a great parallel for what the Engineers were doing with Earth. Consider the difference between how David is treated in Prometheus, and how Bishop is treated in Aliens. Something has happened. Could the opening scene of the movie be an act of great compassion, could the Engineer be sacrificing himself to save the Earth? Could there be some kind of dispute among the race of what to do about Earth. Could humanity be a form of bio-terror for another race? Or a testing ground? Do the Engineers travel faster than light? Are these Engineers acting as part of a greater organization, do the Engineers still have a planet intact? A good sequel will not answer these questions so much as use them as a stepping off point for many more interesting questions.
