Grey's Anatomy, Glee, Dexter, Royal Pains, Law & Order: SVU, The Office, In Plain Sight, True Blood, Nurse Jackie, Big Love, V, Weeds, Rookie Blue, Degrassi: The Next Generation, Skins, Pretty Little Liars, Covert Affairs, and White Collar. Those are the ones that I can think of right now. I enjoy watching TV. Obviously these are all at different times of the year too. :P
I did like Flashforward, but it got cancelled!
