And plenty of people have time to relax and watch a 3 hour movie. They wouldn't make them otherwise.
The again I also find the idea of turning on a show or film just as background filler/noise to be quite weird as well but many people seem to do it so I guess I'm the weird one for either paying complete attention to a film otherwise I find it distracting

if it's good I'll rewatch it, if it's something I've already seen then I'm not missing anything at all. There's so many movies I've turned off when the beginning is boring, it's a decent way to watch new movies and it's how movies on TV used to work.
I'm trying to watch Robert Altman's filmography slowly, and there's so many slow 3 hour movies that watching them in small pieces until they click and actually make me interested in the entire thing helps. if it's all action or something maybe it seems pointless, but some films are a very slow burn, and this helps.
also it's not just movies, but TV too. I would use the shuffle button on comedy shows I've seen a million times before, now tv style drop in works just as well as that when I just want a laugh but don't really care what episode of something I'm watching. now I don't even have to pick a series, I can just pick a channel labelled comedy.
did you grow up with cable tv? maybe it's generational or regional thing
