Orange is the New Black if you've got Netflix. There's also Breaking Bad, 30 Rock, Community, Arrested Development, American Horror Story, Archer, Scrubs, Six Feet Under, Venture Brothers, Fullmetal Alchemist...
I highly recommend watching Arrested Development, The Office, and The Walking Dead if you have netflix. All amazing shows
Intelligence. Debuted last week, and the first episode (imo) was freaking awesome. I definitely think it's on my list of "weekly shows I must watch".
Grimm, Doctor Who (sorry, I couldn't NOT suggest it), Justified is really good, uh... I'm working through Buffy, the Vampire Slayer right now. Being Human is really good. Person of Interest is pretty cool. Eureka, Warehouse 13.
