It's way simpler and more straightforward than you might think! "What I don't understand is, why is there not a script editor who is hired before shooting begins, to read the script with notes as to if or not it makes basic narrative sense. This seems like a minor storytelling investment to make. I should not have to read some dude's insane 4500+ word Space Jesus theory (WHICH IS WRONG) about Prometheus after the fact in order to understand Prometheus. Prometheus should make sense on a basic storytelling level." [The Awl]
