I have stopped watching many TV shows, and now just flip channels until I find something to watch (usually cooking or home shows), but my not to be missed shows are Chuch, Castle, Modern Family, and Wipeout.
Breaking Bad is one of the best tv-series of all time, the acting is top-notch and I think everyone should watch it! Also Homeland is really, really good (with Claire Danes). I watched all the episodes of Homeland in two days because it's that exciting, I can't wait for season 2.
I got reminded of this thread when I watched the latest episode of The Secret Circle. It's one of those shows that's a guilty-pleasure to me, one that I'm not proud of that I watch (I'm 26 years old!) and sometimes I even roll my eyes when I'm watching it since it's so bad... Still though, I can't stop watching.
Let me preface this with the fact that I don't own a TV. I watch the three shows that I still care about online (and have Netflix for older stuff and movies). One of "my shows" is online for free, the other two, I purchase via iTunes Season Pass. SO convenient and MUCH cheaper (for me) than cable was.
RuPaul's Drag Race (online for free, usually the same night it airs)
Sons of Anarchy (usually available on iTunes about three hours after it finishes its first airing on the West Coast)
Archer (usually available on iTunes within a day of airing, sometimes faster)
Sons of Anarchy, Bones, Boardwalk Empire, Fringe, True Blood and pretty much anything BBC. I don't even have cable, we buy a ton of seasons of DVD and stream online.
