Non-Comedy
Game of Thrones
Love it except sometimes it has depravity that adds nothing to the show, at least for me. I skip Ramsey torture scenes, for example. There is a scene where some guy plays a joke by sticking his finger in another guy's butt. I mean, c'mon. Adds virtually nothing. But, the show has me riveted so often. Such a substantial creation by Martin.
Carnivale
Man, I just love this show. I'll always go back to it and rewatch now and again.
Twin Peaks
Others:
Mad Men (am watching it now), The Wire, True Detective Season 1, Battlestar Galactica, Kung Fu (Kwai Chang Cane perhaps my favorite character in TV), The OA (and love Brit Marling), Better Call Saul, BB, Deadwood
Comedy
Really unsure. Frazier is certainly up there.
I am looking forward to checking out Arrested Development.
