Dexter and Modern Family are the only thing I watch anymore on television, so I'm a little biased. Dexter will most likely get my vote, even if this season wasn't ground breaking (I liked it though).
Any other show I watch is something I watch occasionally (a cartoon, The Office, Scrubs) or something retarded (Cougartown, Gossip Girl,.....Grey's Anatomy....).
My horrible confession? I never got into Lost.
