People buying or using TVs have long since associated screen size with cost of the device, among with other features, design and quality, of course. Screen sizes above maybe 50-55 inches have been ridiculously expensive in the past and easily reached up to the price of a brandnew small car. I don't know how many years ago that was, but I do remember some very few 60 inch LCD TVs being presented in electronics store as flagship devices and to lure, awe and upsell customers through anchoring their expectations to large sizes and prices to match, costing upwards of 8.000-15.000 EUR. It has certainly anchored my own association of "very large TV" with "very expensive" connotated with "top earners far above middle class" and "business customers furnishing C level meeting rooms".
I'd expect that not everyone has realized these are sold for 500-1.000 EUR now or rather they've seen it as an opportunity to finally buy something they perceive as being "upper class wealth" at a ridiculously low price, one that is even lower than a month of groceries for a small family now.
People who remember spending 2.500 EUR for a TV may set their subconscious budget to that when buying a new one today, what leads them into the 85 inch range of TVs. The picture will probably be spectacular with 4K resolution and quantum dot local dimming panels and more than just a few other bells and whistles - and expecting to pay as much anyway, why wouldn't they not min-max and buy it, if it'll fit in the living room at all? So they get 80+ inches. And the other group that's mainly focused on the price when looking for a new TV will also min-max, and probably land at the 60 inch mark somewhere, because first, a larger screen outshines a smaller one almost always, picture quality is pretty good anywhere now and bigger = better is hardwired into everyone's brains, so why not, they think?
It's not "just" about "movie night". TVs 60 inch or larger will dominate 99% of all the living rooms they are placed in. Even today's "small" 40 inch displays stand out a lot, even in living rooms on the larger side and will capture pretty much all the attention when they're on, no matter where people sit in that room. But they can still blend in the background while they're off, depending on the room's layout and furniture placement, especially the seating. TVs 60 inches or larger will never blend in the background and will distract people and attract their gaze even while they're off. Seating will be placed and oriented mainly in respect to that screen. Seating arrangement, room and furniture layout will imbue the TV with an absolute dominance over the room and make it into the key element of the entire apartment. Even while they're off, they disrupt human interactions that way. But people will often switch them ON, because they're looking at it anyway and it's just the touch of a button and their dopamine receptors crave for it much more than they realize. And once they're on, they transform all n:m interactions of people in the room into a mode of 1:(m+n) until a very important social function comes up or people have to leave the room for work or sleep. For underclass and NEETs, this is "never", so the thing is ON for every waking hour and they probably even sleep with the TV running more often than not. Designers of upper class TV models have realized this and developed TVs that very convincingly look and "feel" like actual artwork while they're "off", so people will rationalize buying them - and placing them on center stage to be more lured into switching them on more often and be hypnotized later as effectively as the "plebs" who now have largest wall of their living room into a display that shows equally large human heads who tell them what to think and feel.
The only way to win is not to play. Do not buy a TV at all, or at least not that large, and yes, choose, place and orient furniture according to social functions that should happen, so they make them happen or at least don't impede them. Don't buy a TV too small, because then it'll be on even more often and even if it's not hypnotizing people so much, it might become a permanent companion and then develop a similar influence over everyone.
Movie night should be done with a projector and a signal source that has no significant "smart" function or is a low-powered general purpose PC or similar general purpose item. Maybe even a makeshift connection to the laptop when and only while movie night lasts. In my personal, probably mainstream-incompatible opinion, of course. When it's dark, the picture large and the movie great, then the experience will match that going to the cinema pretty well, especially when the sound system is good enough. It encourages installing a sound system, because there's no tinny speakers included like with TVs, where people often skimp on buying a reasonable speaker, because they already have a tinny one for free. The fan noise and darkness required help to curb TV addiction so that "movie nights" are more easily limited to both, movies and nights. The few additional steps required to turning the setup on and starting a program prevent habit-formation and disrupt the pipeline of "being in the living room --> turning on the TV to watch whatever --> pigging out until bedtime while being brainwashed by corporate media". Also, the living room now has one large, white, clean wall that makes everything a little more minimalistic. And people will not subconsciously orient all their sitting furniture towards where the screen will be and not form an "audience-like" sitting arrangement. With no dark screen around, family and visitors will seat facing each other, turn their chairs around and disperse to form a circle, a socially-focused sitting arrangement. People won't do that with a door or large window behind their backs, and their subconsicousness counts a screen like a door, even while it's off, "because it might turn on later".
Imagine to back be in olden times or think about more traditional cultures. Where will heads of households, honored guests sit or important showpieces like family portraits, religious symbols etc. be presented there? Exactly in the spot where Western society puts their TV screens. And we wonder why Normies believe everything it spouts.
Good luck trying that in The-Simpsons-style American houses, though. These are specifically designed and engineered to have the TV at the center of life and in every room where people would sit or lie down. It'll probably feel awkward for a while when removing the TV and waiting for the reorientation of the sitting arrangements to suggest itself.
