It may come to a point where good copies and streaming of all movies are available on their release date and readily available to most people. At that point, theaters are not going to sustain themselves on just the movies that demand to be seen on the big screen. A local theater already closed up rather than affording the price of the switch to digital. They've fallen back on having 15 minutes of commercials before the movie starts. Drive-in theaters faded long ago.
There may come a day when you'll have Imax but the run of the mill neighborhood theater will be obsolete.
I don't know where the maximum profit lies for movie companies. That will be what makes the decision.
What are "ordinary" movies? Because I can think of a lot of smaller movies that are better directed, and would be better on the big screen, than many Marvel movies.
Of course not. It's a social experience for many people. Sharing in the delight with strangers is rewarding. Plus there's the ritual involved in buying snacks.
I won't miss the cell phones, loud rude talking/yelling and the 15-20 minute ads & trailers (all byproducts of the last 10-15 yrs). I will miss the communal excitement of a premiere and the audience reactions to a film which make it part of the experience. Kids are missing out if they think yelling, talking over the dialogue while playing with their tablets/phones and only looking up at the screen occasionally equals the movie experience for them. If you are a parent and never take your kid to the cinema to actually watch a film, then not only are they missing out on an experience but you are probably contributing to the culture of ADHD dismissiveness that occludes anything productive or worthwhile.
Once they work out the technology, I think that theatrical interactive gaming movies will be quite popular.
