I don’t know. We had Walking with Jesus shown a few weeks ago and it was packed with old people. (H walked in for a moment out of curiosity.) But there may be more than just age demographics going on there.
At our theater now, you have to pick your seats and you can see how many people are in the theater and where they are sitting. And if you’re not comfortable they will give you a refund.
But then I also have worked in a room much smaller than a movie theater with 8-10 unmasked people all day since June 2020. I figure a 2 hour movie with 4-10 people is ok.
