This is my least favorite of all the 2012 movies buy far.
I felt the entire team on Prometheus did one heck of a cruddy job.
There's been blame back and forth between the writers and directors, but I suppose when it comes down to it, it's all on the director -- Ridley Scott.
Supposedly, it's all gonna be fixed for the sequel. We'll see.
They probably would have just showed the entire movie if they were allowed to, but check out over 4 minutes worth.
