When watching a show a while after it’s released you can sometimes tell when a show was canceled because a season will end on a big (occasionally spiteful) event.
The following season after it’s picked back up occasionally stumbles a bit but I’m wondering what examples can you think of that were especially bad?
I’m not sure what you’re describing is a common thing.
Writers are known for spiting their viewers like that. They would rather close their story lines.
