Yes, but those are still guesses and catered towards a small movie buff audience. Netflix has the data and the algorithms to know exactly what a larger audience in a specific area wants to see. For example, a certain amount of people in a town add a movie to their Netflix watchlist, and it gets screened in a nearby theatre, those people get a notification telling them of the showing, and they get first dibs on tickets. Most of the cost of the tickets would already by in their subscription. Netflix would be capable of catering to their audience like no other theatre ever. That's the way you make money these days with the saturation of entertainment by catering to a specific audience, but make that audience as large as you can.
This is all hypothetical because it probably won't happen, but Netflix has also been willing to spend money on their product, so they could do things like buy the rights to show Sunday Night Football or the NBA Finals. They would make a ton of money on beer and food every Sunday.
I think it would be a lot of fun to watch something like Stranger Things in a theatre every week. Netflix would be willing to break the mold and try things like that.
Edit to add that Amazon could go stuff like this too if they wanted.
