I live in a market that has about the highest percentage of 55+ of any rated US market. On my street, all of us are over 55, even if it is not a retirement community... and none of us have been to a movie theater in the last thirty-some months.
But nearly everyone got new and larger flatscreens... the ones that didn't already had them. In asking about returning to theaters for some movies, the uniform response is that it's no longer necessary. Interestingly, the biggest negative in regards to theaters is not the health concern but the behaviour of younger attendees who constantly talk, check their texts and do other distracting things.
While that sounds a lot like "get off of my lawn", even prior to the pandemic we had almost totally stopped going to movies for that reason; the experience had been more of an aggravation than a pleasure. And I can make better popcorn at home with my proprietary peppered butter sauce!
