The fact they get cancelled seems more about the business then the quality of the shows. There have been pretty funny shows with some good potential. It really takes a few episodes to get going and some of the really good ones may take a season to get in gear.
I keep telling everyone to watch my favorite sitcoms. (Please watch Abbot Elementary and St. Dennis please). There was more that I really loved that got cancelled. RIP Stumble and Welcome to Flatch
