Well, Sopranos, etc. were the old days. A modern (made in the last 2-3 years) streaming series has 10 episodes per season (or less), and production constraints are publicly acknowledged (usually blaming the pandemic or remote working). So I’ve adjusted expectations based on those clues, given by the production companies themselves.

But quality was going down before that (GOT is a good example). Even on Star Wars TV, the quality drop from Mandalorian season 1 to season 2 and BobaFet is obvious.

Indeed I’ve come to expect mediocrity, but can still enjoy a series as long as it isn’t boring or completely stupid. I simply don’t attach myself to any series as I do with a movie (where I do expect some quality).

(There’s no blame here - it’s fine if you don’t like it or if it doesn’t match your quality standards. These are just opinions, each person will have their own and they can change 😉 ).
