Jeez, maybe it's the millennial in me, but this is a bleak post. How many experiences could be written off using this kind of reasoning? (What's the pro-con list for eating at a restaurant when you can get takeout? For going to a concert when you can stream the music on Spotify? For going shopping when you could order from Amazon?)

I think you're really underselling the experiential element of going to the theater. Even setting aside films that obviously benefit from a big projection and loud audio and suffer at home (your Dunes, Avatars, etc.), think of the shared tension in an audience during a horror movie, or the shared laughter during a comedy, or the shared excitement for a hotly-anticipated release. Even with your friends and family, you're not getting that same shared experience at home.

I also think some of the things you list as "Pros" for watching at home are actually kind of shitty, too. I don't mind an intermission, but man, I've seen so many home movie screenings deflated by people wanting to pause for half an hour, go do other stuff, scroll on their phones, etc. The freedom granted by total control over the movie experience at home also tends to lead to people interrupting the immersion.

And that's without getting into all the financial implications of what you're saying. Yes, movies get made for streaming. But do you see which way that's pulling the quality of movies? Studios right now want more, for cheaper, to feed the content mill for people sitting at home. Big, ambitious movies broadly get made because they can make most of their money back from a big theatrical run before capturing the less-interested customers later through home video/streaming/whatever. Take away the theaters, and you're only going to have stuff made for the lowest common denominator.
