It’ gaining traction in 'Always Sunny' fic circles lately, I've noticed. The classic dynamic used is about exploitation versus a weirdly sincere fascination. Dennis sees Winnie as this ultimate project—a blank slate he can manipulate into his perfect, admiring audience. But the conflict often spirals when his own narcissism gets bruised. He needs her validation to be real, not just programmed, which of course it can't be. So you get these arcs where he’s furious she doesn’t genuinely fear or adore him, just reacts to inputs. That’s where the quieter, sadder fics come in, where his rage masks this pathetic loneliness. He built a doll for company and then got mad it was a doll.
Writers also mine the horror of Winnie’s perspective, or the lack thereof. Is there a glimmer of personhood in there? If so, watching Dennis systematically override it is deeply unsettling. The emotional core becomes about violation and erased autonomy, played totally straight and tragic. Or, in darker comedies, it's about Dennis becoming increasingly unhinged because his 'perfect woman' is, functionally, a prop. The comedy comes from his downfall being a talking sex doll he bought off the internet.
