@Jessicacrets hard agreed. the actual alien bits are eh, and the "people are infected with space spores" bits are kind of classic "don't touch that please don't touch that c'mon dude have you never seen a horror film DON'T TOUCH THAT"
but all the sort of self-indulgent, introspective stuff about androids and human nature and stuff was pretty dope. and scott is so good at making pretty movies
