It's seems clear to my family and friends that they have some sort of checklist for writers that includes garbage like mandatory regular sex scenes. In my case, they have _finished_ a tiny tiny percentage of their shows. They tend to string viewers along with contrived new-but-very-similar problems each season, and then just cancel once viewership gets bored. No thanks, give me a show that has an ending.

I think Disney has been better with their series in this regard. I've been watching a few shows that were planned with many seasons in mind, but instead of abruptly pulling the plug when viewership was lower than expected they gave them a final season that writers have been using to wrap things up really well. I can start a new show from them with a bit more confidence it'll get finished.
