I'm a huge Game of Thrones fan. I read the books years back so it's always a blast to watch it with people who don't have a clue what's going to happen. Now the series is catching up with the books and some storylines are changed / new altogether so this season I'm seeing some unexpected things too.

Other shows I enjoy:

Vikings
House of Cards
Penny Dreadful
Face Off
Stargate Atlantis
The Tudors
Weeds
Welcome to Sweden
Real Humans

I also love watching documentaries, especially history, archeology and the like. Also travel shows. I love the ones done by Anthony Bordain, An Idiot Abroad and The Long Way Round / Down.
