Breaking Bad - Saw the first four or five episodes of this, couldn't get into it, and I find the idea of the protagonists being meth dealers unnerving.
Game of Thrones - Fave show. Season 3 wasn't as good as previous ones but I'm holding out hope. Normally I am not really big on violence but somehow it's more acceptable in a fantasy setting.
Boardwalk Empire - Haven't seen
Mad Men - Saw one episode, hated every character with a passion
The Walking Dead - Finished season 1, haven't gotten around to watching season 2, wife isn't interested because it's zombies
Homeland - Haven't seen
Justified - Haven't seen
Modern Family - Haven't seen
Sherlock - Saw seasons 1 and 2 on Netflix, highly anticipating the third season
Other (Please Specify) - Started watching Continuum but it's been fizzling out. I love the premise and the idea that the good guys aren't all good and the bad guys aren't all bad, but the show itself just hasn't captivated me.
EDIT: Oh and Girls, on HBO! Great show.
