AI versus Prometheus

A.I. was a good movie and i can`t understand why there is people who didn`t like it. It was sophisticated story and with deep philosophy. Very touching movie, with many layers. I can find in it a lot of questions and i definitely want to think upon them. There is a few more movies even better than A.I. Prometheus on the other side is with primitive script with a lot of irrelevant questions and i don`t feel the need to thing about them. So why the engineers want to destroy us. I don`t care because i will see it in the next sequel maybe. Why i must think about that ? This is not a deep question. Deep questions stuck in your brain and you think upon them and try to find your answer. You speculate with the answers that Lindelof will give you in the next sequel. How deep is this? I really wanted this movie to be epic. Not to be very intelligent, just epic but it`s not.
