Some films are meant to be watched in large formats with insane audio that just can’t be replicated at home. The Dune movies and Oppenheimer are a few recent examples I can think of that looked incredible in 70mm IMAX. I live in a major metro area and there are only 3 screens within 50 miles capable of showing 70mm properly. I choose to go out of my way to these theaters once or twice a year, if a great film is showing.
Short of films shot and shown in a true large format there’s no way you’ll find me in a theater.
I’ll watch content on small screens if I’m on a plane. Otherwise it’s my 80" living room TV with passable surround sound.
I guess it depends on what you consider passable.
It’s loud enough on 25% to disturb my neighbors, it’s clear and defined enough for me to watch normally and hear everything at 7%. There’s no observable delay, and the installation is clean enough to make my wife happy. It wasn’t cheap, but I wouldn’t consider it expensive.
