I don’t think pricing is the only problem with theaters. Especially over the last 15 years or so they’ve been increasingly competing with alternative ways of watching movies, and for a lot of people watching at home wins at any price.
Fancier theaters like the Alamo draft house seem to be trying to complete with watching at home in some ways, but for the most part theaters seem to just be doubling down on the parts if the experience that were already decisive- namely getting louder and adding bigger screens. That might tempt the people who already like what theaters have to offer into going slightly more often, but I think it’s made even more people stop going at all.
