Beautifully written and you gave me a lot to chew on. And I think your hopefulness is justified. I just saw the movie Tar and I think it achieves the kind of "artiness" you describe, at least in terms of ambiguity. Was expecting a political "Me Too" movie but found an exploration of genius, madness, and ambition that didn't take clear sides. Of course, one conservative critic cherry-picked a scene to dismiss it as a progressive movie while a progressive critic cherry-picked another scene to dismiss it as a conservative one. Would help a whole lot if we took in art with our blinders off (and that would include me).
