This is easily the most fascinating and delightful movie Coppola has ever done - it's clear that anything that's deeply experimental isn't going to be for everyone. And especially not for the masses.
People have been watching conventional (i.e. not experimental) movies for so long, some of them may no longer even appreciate what it is that makes experimental films worthwhile. A few years ago, I did a huge binge watch of all of Godard's films. My impression is that he became way more experimental in the later stage of his career. Some of those movies can be challenging, maddening, and frustrating at times, if you look at them from the point of view of "conventional narrative". And yet, they are also, imho, enormously rewarding, because they are the clear signs of a unique point of view, alone among all of the greatest filmmakers who have ever lived, who clearly wasn't happy with the status quo. And sadly, many of his later films didn't even get a theatrical release in the US.
In short, if you're not feeling adventurous, or if you think the IMDb scores are the best way to gauge this film, definitely do not buy a ticket for it. It's very possible you may find the movie frustrating, incomprehensible, or both. Or just don't watch it for any other reason that I haven't mentioned.
Did it ever occur to you that he might have posted that to give us some information about the film, which is what you've been doing all week? At least the info he posted was interesting. Did it also ever occur to you that he knew it would get under your skin, regardless of whether or not you'd admit it?
The movie's getting negative reception everywhere. You're gonna have to deal with it like I do, because challenging every time someone doesn't have anything positive you say essentially means it's you against the world. And I doubt you're ready to take that on.
