Yeah, I think covid broke the habit for a lot of people but it's been a strained relationship between theatres and the viewing public for years.
movie tickets and popcorn/stuff for 2 is like 40-50 bucks, obviously less convenient than staying home, most movies aren't really worth making an event out of unless you love the theatre experience. Theatres are the same cookie cutter corporate bullshit so there's nothing really unique or interesting about going....oh, your theatre has a small arcade section I can drop 20 bucks and shoot a couple of free throws at? Cool. Obviously the size and quality of the screens we watch at home have changed as well...back when I went to theatres a lot as a teenager I had a 20 inch box of a TV in my room as the alternative if I just wanted to rent the VHS tape instead. Parents might have had a 30-35 inch box in the living room with standard potato resolution. Now most/all of us have anywhere between 42-70 inches of 4-8K flat screen technology strapped to the wall.
So yeah, as an experience it's become mediocre in both form and to a degree, content (most movies really don't need a full theatre screen to be enjoyable, it's largely CGI fests or big cinematic action flicks that show better like that), and if you're selling me the same or similar content that I have fucking mounds of at home, the experience should be worth it and it just isn't.
