Tonight was the series finale of perhaps one of televisions greatest shows of all time, Hannibal. Hannibal was so well done with brilliant performances and writing that it became a critical darling and found a devout following of fans. Unfortunately the ratings weren't there and after 3 seasons NBC pulled the plug. It's not the first time something like this has happened. Shows like Firefly and Almost Human were really something special but they didn't make the cut for additional seasons. What are some shows that were cancelled ahead of their time that you'd love to see still on the air? On the opposite end of the spectrum what are some shows that are still on that make you wonder "how the hell is that crap still in production?"
