Game of Thrones...
I don't have HBO because I just think cable/dish is just too expensive as it is, but I have a friend who signed up to just watch TrueBlood. He gave me his HBOGO signin and I have spent the last couple of days watching season 1 and season 2 of the series. IT IS FREAKING AWESOME. I have always loved period pieces like that and all of the backstabbing and conspiracies. I just love it. I hope he keeps HBO when/if season 3 starts so I can stay up to date.
