I see. A subversion (Subversive, maybe, would be a better word) to be sure, but not the kind of one I'm thinking of. I'm thinking more along the lines of hyping up a romance between two characters for the entire series, but then Character X decides to go Gay/lesbian, join a Polycule, or live alone in the mountains as a cat-owning CEO instead of giving the audience catharsis. Yeah, that subverted my expectations; it also told me I should go fuck myself and the show runners do not respect my time.
Like Helluva Boss: It's about IMP Assassins. But then in season 2, it's about Stolitz, and will continue to be about them in season 3.
