What Shows Would Have Improved If They Have Less Episodes?

Bocchi the Rock is another show that I felt would be at its best if it stopped at episode eight. If the upcoming compilation movie stops there, I may consider it superior to the TV series. It's not unheard-of. Violet Evergarden's film-length recap stopped at Episode 10. ::: spoiler I want to see more of Bocchi-chan's rock! The title drop + roll credits is its peak and climax. I hoped its finale would be amazing. However, episode eight overshadowed episode 12. Everything after E8 felt like a lede for an S2. :::

What are yours?
