After rereading my comment I'm sorry that I started out so aggressively. That wasn't fair to you.

I think the feeling of fewer good shows coming out stems from a few places.

1. The shows that we remember tend to be the ones that left a lasting impact. I think that when looking back it's important to recognize our nostalgia tinted lense.

2. The feeling that there's so many more shows may come from the accessibility that streaming services have created. Scrolling through massive catalogs let's us see the massive amount of options and how few of them we actually want to engage with. I'd argue that the ratio of good to bad shows isn't substantially different from before, but how we engage with these shows have changed. Admittedly, I haven't counted all of the good and bad recent shows and then compared that with the amount of good and bad shows from a couple decades ago.

3. "They don't make shows like they uses to," is the type of thing people have said forever when their tastes stop developing and the cultural zeitgeist moves on without them.

In addition to the shows you mentioned, I would add, The Bear, The Last of Us, Arcane, and Our Flag Means Death.
