Orange Is The New Black, The Walking Dead, Game Of Thrones were all great. Another less known series, Revolution. I thought was great until they cancelled it and had to use a premature ending.
Breaking Bad is easily up there, The Simpsons will also hold a place in my heart forever. I also loved The Following, S1, haven't seen S2 yet but I wish they kept it down to one series. And American Horror Story: Covent(?) was superb.
