What's a show that should've gotten cancelled or ended SOONER than it did?

Casa de Papel. The first season is its own contained story and it was fantastic and ended perfectly. The subsequent seasons were okay, but you could really tell that the writers hadn't expected the show to continue after season 1, and everything kind of felt made up on the spot and not nearly as well constructed. I watched it because I love some of the actors/characters, but when I recommend it to people, I tell them to only watch the first season.
