I will get hate for this but hear me out.

Sex education.

First two seasons were epic.

The third season they introduced a fully rainbow school that absolutely ruined the show. It turned into a challenge to tick every box at the same time instead of being a good tv show that had those topics as part of the story

I have no issues with the content, but it didn’t feel like it was part of the show, it felt like a big giant participation award instead.
