People I grew up around who were in to that finance, suits, coke, hookers lifestyle portrayed in AP, they all loved that movie. Bateman with the axe as cover photo on facebook. I've always thought of that affection as a some kind of rosetta stone for their psychology. It's a bit weird to be in to a movie that satirizes something you like of course, but when you really get what they're about, it makes perfect sense.
It signals exactly the kind of detachment from any kind of inner or deeper meaning or morality they seemed to deify. It's not only a mocking of the attempt to criticise them, it's that they really don't care. You could call them reprehensible and they'd savor the fact that you're expending attention and energy at their command. Their only sacred doctrines are attention, interest, outer significance. Making a movie about them bolsters their confidence that they're at the center, whatever the intention. Money, external success, is the prime index of that doctrine and becomes the sublime object.
Since I loathed that whole ethos, I always wondered how you could actually get a punch in. I guess the only way is to deem them boring. To not care about them at all.
