Does Ridley Scott know what he's doing?

MemberOvomorphJune 17, 2012752 Views11 RepliesInteresting reading the threads. Reminds me of all the talk about the Matrix movies. I have to assume R.Scott has thought out the other 2 movies very well. Just to make the movie as ambiguous as it is must have required hours and hours of talks with writers, producers, actors, etc. So I assume like the Star Wars movies it's all pretty well thought out. HOWEVER one thing bugs me and makes me lose a little confidence. I can make lists of questions like everybody else but I just wanna talk about one thing that bugs me. Maybe it's NOT so well thought out.
Engineer/Space Jockey proportions:

I could not find a human next to "Prometheus" Space Jockey picture. Everybody probably knows that they used kids in suits to ramp up the scale of the space jockey for the ALIEN movie. But something got seriously lost in the "Continuity" department.
Couple of other questions I haven't read yet.
1). Why did the engineer chase Shaw in the end. Why not just use one of the other ships in those silos and take care of her from above?
2). If they created us why tell ancient man how to find them, and then be hell bent on killing us? I don't think they wanted us to find them. Cave drawings that you hope people find, and I still don't get how that would help anyway.
