That scene needs some rework, the engineer ripping of the androids head needs some dialogue like they originally intended, Guy Pierces old man get up need some CGI touchups so it can at least be as believable as Bad Grandpa. Theres probably some other things that I'm forgetting.

I will give it credit. It definitely tried to be something bigger than just chestbursters and jump scares. It was a pretty bold prequel.
