I saw it and the theater had 6 Gen-X/Boomer white men in it, my weird self and SO (who wanted to leave), and a group of 4 millenials mocking the movie in it.
First hour was pretty engrossing and the end is wild but I get why it's hard to review. It's definitely a mashup of all of Francis Ford Coppola's favorite things and complaints he has.
But it's an optimists dream like view of reality. It's akin to Inside by Bo Burnham, except far more hopeful and less pointed, and more like a club to bludgeon you with the message with.
I kinda wish he had an even more limited budget to work with to inspire some real avant garde creativity but I'll take what we got.
I don't think it needs to make it's money back. I don't think that's what Coppola was going for. I'm not sure it will even be a cult classic (kinda depends what society does next) and I think that side thought is basically all of Coppola's point. His medium to talk is just that of film.
