Not everyone is an avant garde movie enthusiast. Some still enjoy the fun and spectacle of action films, superhero films, Star Wars.
I am among them. I make no attempt to say they’re high concept or anything, but I leave feeling good for awhile and that’s enough for me
It's like eating a burger - they're basically all the same, but there are variations. And a burger isn't anything amazing (even if you find a pretentious one, it's still a burger), but it's still nice to go out and get one now and then.
So maybe I want to watch some capeshit today, but I don't want it to be exactly the same as the ones I've watched before. Many people feel this way, and the market provides.
