Shows eventually run out of steam. It goes from some creative idea somebody has had to a 30-60 minute slot of time some writers are tasked to fill which leads to formulaic writing without much energy or creative spark, just a product that's been created to a spec.

This is especially the case with procedural shows that have 18-24 episodes a season that is designed to be a collection of one-off episodes where the writers have to be sure to include certain moments that are signatures of that particular show. There is only so much juice to be found in a certain set of characters or setting and in the end they're just grinding out episodes to wack on TV.

As a viewer eventually the artifice breaks down and you go from being engaged with the story to spotting what the writers are doing and why. You see contrived plot devices that were purely designed to extend the show's run for example.

It's why mini-series like Queens Gambit or serialisations like Breaking Bad are good. They have a self-contained story that is the idea of a few creators and once they've got it out of their system, it's done.
