Not sure movie theatres will be ending, there is still something special about the “Big Screen” experience that is not the same as watching on your home TV, and as far as cost it is still relatively cheap entertainment at $13
It matters where one lives.
I have diversity near me, with access to free bus passes, so movies are done forever if I live here.
You have to fill up the theater regularly or you can’t afford to stay open. I don’t believe theaters will ever be able to regain their former popularity. To many viable options available. They’re history sooner or later.
