“Happy”, I think a lot of people overlooked it because Christopher Meloni having a cartoon unicorn as a companion seemed cheesy, but the show wasn’t afraid to dive into truly horrific plot lines.
The less-grounded corner of my brain thinks the show was cancelled because it was openly talking about skeletons in the closets of network executives.
Whatever the specific community currently agrees is the best method for success, like strategies for video games, gimmicks for social media, etc.
