I mean, don't get me wrong... streaming is still pretty good. Fragmentation of content aside, there's more good content than there's ever been. So I'm not a 100% doom and gloomer...
but...
Getting that content has the "provider" problem. As you say, whack'a'mole to get the movie you want.
People always bitched that "Cable is horrible! Why do I have to pay for 400 channels to get the 3 I watch!". And here we are... able to pay for "Ala'Carte" and it's exactly what everyone wanted - and expected: Paying more for each bucket. Instead of $100 (or whatever a full cable plan is)... you're paying $75 for internet, $15 for netflix, $10 for prime (or whatever it amoritizes yearly), disney+, hbo max, Discovery+, etc, etc, etc.
Finding the EXACT movie you want is a hassle... and that hassle is what drives me to Plex. Radarr/Sonarr/NZB/etc all roll together to make a massively good platform that, learning aside, hands all the power back. I do have to pay for some stuff (NZB, Plex, internet, time learning, etc) but it's my time and worth it.
