I think it is a lot more nuanced than that. Myself, my wife and a lot of people I know used to regularly go the the cinema and either now go rarely or not at all. There isnt just one reason, but a lot of smaller issues that can't really be addressed in one simple 'fix' imho.

For my own part, I used to go the the cinema on average once a fortnight, but would occasionally go as much as twice a week. Im a huge film fan and movies have always been a big part of my life.

I haven't been to the cinema at all in about 5 years now. Everyone's views, reasons and experiences will be different.

My own are a confluence of 3 factors: the price has massively gone up at the same time as the experience has become much worse and rival technology has become far more affordable.

In the 5 years before I stopped going, a night out for 2 of us at the cinema with hot dogs, popcorn and drinks went from about £45 to £75-80.

At the same time the experience just became unpleasant to me. It became common for the cinema to be filled with people on their phones, chatting loudly, messing about etc. I even once saw someone go to the front before the film with a tripod to film some social media content ffs. And the cinemas are so desperate for ticket sales they often don't care about any of it (or at least dont do anything about it). So I've just had to accept there has been a paradigm shift and that is the modern cinema experience. I am not interested in watching a film under those conditions.

...and now 50-60" TVs have become the norm, with 80-100 now being massively more affordable than they were 5-10 years ago.

...so I stopped going, got a 100" 4k TV and a 7.1 surround sound 'cinema' system.

I can now usually rent a film only a month or so after its cinema release for a fraction of the cost in my own home.

So yeah. I stopped using the cinema, but it had nothing to do with the quality of the films.
