Jordan Peele has since cleared up what he meant about "Get Out":
Jordan Peele’s All-American Nightmares – Rolling Stone
The "social thriller" tag came as a response to the genre confusion from people not familiar with social commentary in horror.
I mean....who in their right mind would argue "Rosemary's Baby" isn't horror?
The problem with your argument is you're getting bogged down in the minutia of how this film would be classified if it was on a shelf in Blockbuster.
Was "They Live" scary? No. Was it full of social commentary? Yes. Does that make it anything other than horror? No.
Was "Society" scary? No. Was it full of social commentary? Yes. Does that make it anything other than horror? No.
Was "Invasion Of The Body Snatchers" scary? Yes. Was it full of social commentary? Yes. Does that make it
more horror than the two movies above it? No.
So....no offense but I don't even get what you're arguing here. There's not a clear point where you add X amount of social commentary and suddenly it's not a horror movie.
