You wonder why this guy has problems maintaining a steady relationship when the most emotional scene he's ever written, the purest expression of love he's ever managed to capture on screen, features a balding man literally slapping a woman back to life while calling her a bitch in front of a captive, appreciative audience.
It's seriously one of the best scenes he's ever written, I'm not kidding though. Probably because it seems to be one of the purest distillations of what makes the guy tick, emotionally.
(I don't think he's sexist. I think he's kinda tone-deaf. But he's so invested in it that you roll with him anyway)
