I think a lot of shows are AWESOME, but then late-stage capitalistic enshittification happens and they become... far less so, and often quite TERRIBLE even, though ostensibly still have the same title, even though nowhere near being an identical show.

One super-good example is Stranger Things, where the first season was really quite good! So many homages to nerd culture like E.T. and D&D - it was fantastic!:-) As I read though, the pair of creators had 2 rules: never use CGI, and absolutely do not "sell out", i.e. a story should want to be told, not sold merely for the sake of cash. So after the first season where they made it b/c of their love for the craft, you can guess how the subsequent seasons played out (I believe one of the pair even quit over it).

Arguably a better example is The Walking Dead - it started off REALLY good, but then... well... it too "sold out". Actually I keep trying to force myself to get through it, I even started watching it over again from the start (a couple times now) thinking that would help, but have yet to accomplish this feat.

Another is Designated Survivor. It had some big-name actors, most of whom quit (I think the show was sold to a different network... or something?), and the last season was just terrible, limping along before they finally put it out of its misery and ended it.

The really fantastic shows - like Star Trek - had to prove themselves, then the creators were given leeway to subsequently make great sequels and spin-offs and even entirely unrelated titles. Fun story: Gene Roddenberry even created shows after his death, as his wife took his unfinished notes and lead their creation under his vision, like Earth: Final Conflict.

TLDR: why offer you a good show when they can offer you a crappy show that they made for a tenth of the price, yet charge you the full amount?

(though stupidly enough, they also seem to be trying to offer us even more terrible shows that cost 50x the price to make, and yet somehow suck all the more for that!? anyway it all seems to be based on greed + arrogance - they want to make money, but they do not want to put in the effort to actually earn it, e.g. by paying the actors a decent wage)
