They’re fighting a losing battle, but I hope a side effect of it is that new people come in and change both the economics and artistry of Hollywood. Most Hollywood content sits in a very rigid box. It’s repetitive, unoriginal, and unappealing.
My two cents is there’s a structural issue that’s converged to strictly Campbellian story-telling as the end-all-be-all structure. Sure, you’ll have something come out of HBO or AppleTV that breaks it, but AAA movies rarely break it.
Capitalism, actually. The private firms have owners and employees (who might have shares) who look around at the state of the world as is, see how fruitless change is, and decide on their individual gains over the needs of the many. Systemically we converged to a system that blossoms profit, in theory, but doesn’t take in the reality of the world.
