I don't disagree but as the cost of tickets go up, some people expect more entertainment. This is part of my problem with going to movie theaters these days. They charge the same $15 ticket for 3 hours of special effects and star laden Endgame as they charge for 90 minutes of entry level rom com. Theaters are one of the last bastions where you don't actually pay for quality or quantity, you simply pay the same for all of it.
I expect dynamic pricing is only a few years out and I think I've even seen it tested at a few theaters already. It's the only way I can think of to really keep theaters viable. I fully expect within the next 5 years when you get an Endgame type movie opening, you are going to pay $50 for opening night primetime, $40 for off hours on opening night and then see it drop quickly through the first weekend. Whereas the ticket for a theater showing an opening mid-level rom com is going to be $15 and a second weekend Endgame will probably have fallen to something like $20 at primetime and $15 to fill the rest of the hours.
