@KeetI agree with a lot of that. Expanding on 'special ambiance', though, I think what's going to drive the movie business going forward are two things: date nights and event movies.
Date nights will be a thing because people who aren't in relationships are leery of going on dates to other people's homes/apartments/whatever to watch a movie, and people who are in relationships want to get out of the house sometimes and go do something.
Event movies will be a thing because people want to be in the presence of groups of other people enjoying the same thing. You won't get that round of applause at the end at home (or it'll be really different), you won't walk out of it around strangers who just spent a couple of hours immersed in the same world, etc.
The combination will tend to push theaters towards date-oriented fare, feel-good movies, and blockbusters, which seems natural. 'Smaller' films will gravitate towards streaming.
Different, maybe reduced, but not gone.
The other type of theaters will thrive are ones built to cater to that - theaters that serve full meals, serve alcohol, etc, and ones who run 'fan favorite' movies as singalongs or other audience participation events, mix live comedy with movies (think of MST3K, but live), etc. Not anywhere near the numbers you get for a first-run blockbuster, but more than plenty to keep the theater running indefinitely at a healthy profit.
