The entire approach to both scripts, for me, is wrong. They both have done a serviceable job here. It's just the details of the story that I find supremely lacking. I suspect this is mostly on Scott's head. We know that both writer's worked heavily with him on their scripts. We also know from the interviews and the extras crap on the BluRay, that Ridley was driving the buss. I honestly find this movie to be equal parts Alien3 and 4. I think it lacks the intelligence and simplicity of the first two. One think that struck me was how powerful the full TED speech was. It establishes character, tone, and much of the story yet to come. It should have been at the beginning of the movie instead of the sacrifice scene. It was too on the nose. It was too CSI. It was too early to reveal the big blue men. It should have gone straight from the full speach to David watching it on a monitor, then the David stuff. Get rid of the retread of the AVP assembly scene it's dull and adds nothing in the way of character set up.
