The culture war stuff seems a product of the art itself not really having much value these days, what with the whole "poptimism" thing having happened and the resistance to "gatekeeping" making it unacceptable to disagree on aesthetic grounds and suggest something like Marvel is in a different tier to something like First Reformed.
Given the above, it makes sense that the fiercest debates are rooted in the perceived politics of a film and its effect on one's personal brand. It's just a film and one film's as good as any other now, so the focus shifts to its utility as an extension of personal identity. It's not "Is this a good film?", it's "Is this a good look?".
Someone watches and enjoys American Psycho, but they're conflicted because it's a "red flag film" or it makes them a "film bro" or it's too "Reddit". Their opinion of the film gets buried under all this cultural baggage and becomes more or less irrelevant.
