I can only tell you how I personally feel... the movie going experience was way different in 1988 than now. You bought a ticket, sat down, and watched a movie.
Now, the prices are exorbitant, for my wife and I to go to the movies, plus snacks, it could easily be $50 or more. Plus there's an extra hoop to jump through of having to use their stupid screen to pick our seats.
Audiences are different too, they're talking, they're using their stupid phones. It's far harder to enjoy a movies these days and if you're talking a character piece like Rain Man, I doubt it would actually be watchable in a theater today.
I have a 65" 8K television at home with 7.2 Dolby Atmos sound, if you want me to go deal with the stupid crowds, the high prices, and the overall poor experience of going to the movies, then, yeah, it needs to be a SPECTACLE. Some grand adventure that demands I see it RIGHT NOW, as opposed to "Meh, I can wait for streaming or Blu Ray."
By and large, that means your big franchise films.
Look, I enjoyed the hell out of "Murder on the Orient Express" and "Death on the Nile" and I saw them in the theater. I'm not going to "A Haunting in Venice", a) because it deviates from the source and b) because nothing in it demands the theater experience.
The Creator looks interesting, but I HATED Rogue One and it looks like the directors same problems have followed him there. So, no, I doubt I'll ever actually pay money to see that.
