I think Netflix has honed in on the "have something for everyone" strategy. Just about everyone has a show they like on Netflix, but for most people it seems like there's only a few. On your list I only liked Ozark and Money heist, plus Bojack. Meanwhile HBO creates a great show every year, and actually renews their stuff. Disney is a necessity for kids. Apple TV+ costs 25% as much. It really feels like netflix has diversified far too much, and now people are realizing that there are cheaper options that just make the stuff they like.

Squid Game and Tiger King (which has a second season right now BTW) were huge. Stranger Things was huge and keeps promising (but not delivering) a fourth season.
