Hey, it can't be politics all the time, right? There's a thread on Reddit today called "What is your favorite cancelled television show?" and my first thought was "Terriers."
If you missed it - and you probably did - the FX show starred Donal Logue as a recovering-alcoholic ex-policeman now running a detective agency with his former-criminal buddy. It was gritty and funny with sharp dialogue. The critics loved it but the show was axed after a single season.
I think it's on Netflix if you want to give it a try.
