With streaming you can watch what you want and not the "ehh, there's nothing else on" shows. Studios are still making those low effort, watch because you have to if you want to watch anything at all shows, and maybe it's a feeling of not being in a target audience but they are mostly that these days. Maybe even more so than before, because the studios now don't have a reasonable expectation that people are just gonna watch it because it is on.

They have a pseudo incentive to produce a higher amount of cheap lazy garbage to flood the market with something, anything, that might grab attention and become a hit, whereupon they might invest more into it. They've really been lowering the bar, over and over, and as the bar lowers more and more people aren't stupid enough to follow along and just watch whatever. Why watch modern garbage when there are yesteryear classics that were made with passion, at least enough to veneer over the ever-present profit incentive.
