I think movie theaters will come back. Once vaccines get established I think (my opinion) that will be the final straw for almost everyone, regardless if repeated vaccines or new variants evolve that keep COVID going. The overall risk will be reduced so much that people will just start treating it like the flu, government health departments included.
And once people feel free to go about doing what they used to, there's going to be a huge demand for theaters, Chuck E Cheeses, amusement parks, bars, nightclubs etc. just from all the pent up demand.
But I don't think this is going to happen until at least the summer, and maybe later. Unless vaccination programs can really get moving.
