I wonder how much of that is because the movies themselves changed vs everything else that has changed. Back in 2002 most people still watched tv on CRT that were very small by today's standard and had very low resolution. You either had to go out and rent a movie, rewatch something you had recorded or bought or watch whatever was on and enjoy the ads. Now we have a huge choice of movies and tv shows at our finger tips any time. Yes, the screen is still much smaller than in the cinema but I also sit much closer. I can pause the movie when I need a bathroom break. I can eat and drink what I want. A movie has to be really good for me to want to spend $40-$50 on going to see a movie with my wife. No travel required, no sitting through ads, no risk of someone in the audience being obnoxious.

I used to go to the cinema quite a bit. Now I only go once every 1-2 years to see something on IMAX that I hope will really benefit from it. In recent years that was just the two Dune movies and most recently the F1 movie. Unfortunately, even the biggest IMAX theater in my area is still not what I'd consider a proper IMAX like the Metreon in SF so I'm always underwhelmed. Not sure if that's because this IMAX is too small or because even IMAX stopped being amazing due to growth and improvement of other screens.

I used to watch a lot of smaller movies in the cinema. That's stopped entirely. With any movie the question now is how long till we just can watch it at home. Smaller movies which I'd be more willing to support frequently even seem to skip the few months where you have to rent them and go straight to streaming. So unfortunately even less incentive to go to the cinema.

Culture around it doesn't help either. Friends used to recommend movies that they watched in the cinema. I can't even recall when that happened last.
