The next great auteur moviemaker is going to completely eschew on location sets and expensive specia
The next great auteur moviemaker is going to completely eschew on location sets and expensive special effects, but the sets and the effects won't be "bad." They will be abstracted. They will be intentionally phony looking as a way to emphasize other facets of a given scene.
People have dabbled in this so far. Louis CK did it with his HBO series Lucky Louie and the 2012 Anna Karenina movie experimented with abstracting sets but at the extremely high end.
Great story tellers will come along and shoot films on movie sets running their sets much like the theater does but taking advantage of things like musical scores and sound effects. It will focus people in on strong characters and strong arcs.
The arc of filmmaking that attempts to be more and more realistic is coming to an end. It's getting weird. It's in the uncanny valley. Sure probably that problem will be solved but there's space for someone to become unforgettable forever by heading in a wildly different direction.
