Honestly all of those things are usually worse for me at home. I don't know what kind of nightmarish theaters these people go to but mine is usually a pretty great experience.
I was going to say the same thing. What theaters are these? People make them sound like the Wild West, people running around shouting, throwing popcorn, impossible to concentrate. I’ve rarely had an experience like that in recent years. I also don’t usually go to G or PG movies for little kids, though I’m sure I will be within the next 2 years for my son. Maybe try different theaters if you have the option?
But I think for a lot of people (not all), beyond movie theaters, they just don’t like going out to do things in general -- even in a pre-COVID world. They’d rather eat at home than go to a restaurant, don’t often go to bars or clubs, would rather watch stand up comedy at home compared to going to a live show if given the chance, don't care about going to concerts, would watch Hamilton on Disney + but would never bother going to see Broadway shows live, etc. They just don’t see much value in that kind of shared experience with other people, aren’t able to or don’t see value in spending that any extra money than they absolutely have to, and don’t want to be hassled or inconvenienced in any way (leaving the house, driving somewhere, waiting on line, needing to arrive at a specific time, etc) to be able to have that kind of experience, which is fine. The so-called "distractions" (talking, texting, etc) is the excuse most people use, but I think that even if there was a way that you could literally MUTE every other person in the theater, guarantee 100% that no one would take their phones out at all, and meet ALL of their demands for an enjoyable viewing experience, many of these folks still would have no interest in going out to the movies.
For me, feeling the energy of the audience in a packed showing of Halloween Kills on opening night will definitely be half of the fun for that first showing. It won't bother me people are laughing and screaming at the movie or even if there's a little talking at some point, because I can appreciate that it means those people are having FUN and it's fun for me to hear a movie getting that kind of response out of people -- myself included. I love watching movies at home as well and obviously do so all the time, but I always say that I can only see a movie like this for the "first time" once. After that, for essentially the rest of my like, I'll be watching Halloween Kills at home dozens and dozens of times just like I've watched all of the other Halloween sequels.
And these days, even if you somehow DID have a truly bad or not-so-great theater experience when watching any movie, it doesn't take long to be able to watch that same movie at home for a repeat viewing. Most movies now either come to "home video" or streaming same day, 30 days, or just 45 days after theatrical release. I remember the days when it sometimes to 6 months to a year for a movie to come out on VHS to rent or buy. LOL
