Current shows - I can't miss Grey's Anatomy or Glee, that's a weekly requirement (although I do watch them online or on the iPad the next day, we don't have any TV channels)
I also plow through old series or current ones that I am way behind on on Netflix or online. Recently I watched all 7 seasons of "24" (loved), and I am reliving my childhood watching Dawson's Creek (LOL! Brings me back to my preteen days!). I also like Bones, CSI, Law and Order, and an old personal favourite, Gilmore Girls. Oh, and I love The West Wing!
I watch a lot of Food Network ... Chopped is my fav show on there. But I also LOVE Gold Rush, Hoarders and Extreme Couponing. As for "regular" shows, like the 30 min ones - I don't get into those at all. When DH is home we watch Wicked Tuna, Criminal Intent, Law and Order (but only the SVU) and NCIS.
And cops. Hubby loves cops. LOL
I haven't been watching as much lately - but I am a HUGE tv person usually. I have a bunch on my DVR right now, but the ones I always want to watch first are The Good Wife, Grey's, Glee and Big Bang. I will also binge watch seasons of shows - and Gilmore Girls is definitely an all time favorite. Others on my DVR include vampire diaries, 90210 (I'm a huge kid) biggest loser, arrow, revenge and bones. I ran into issues with How I met your mother because there were too many things on at the same time to record them all. So now I'm super behind. And I used to watch a lot more online, but now I DVR more, so I got behind on a lot that I used to watch - oh well, I don't think I really need anymore anyway!
