LOL! You have a strict definition of porn
I need more than nudity to make that distinction. Excessive, very graphic sexual activity or excessive, stomach churning violence. OR sex and violence mixed and over the top--Cronenberg regularly skates that line brilliantly.
Wolf of Wall Street bored the hell out of me, but I don't worship at the shrine of Scorsese, either. I don't like many of the social commentary movies about the 80s (and given by druthers, I'd choose
American Psycho--lol); boring, when you lived in the era.
