BOTTOM 10 NOTE: As I said on the Worst of 2010 podcast with Sepinwall, my Bottom 10 can only include shows I watch regularly, or at least semi-regularly. There are probably worse shows on TV than some of the shows on this list, but these are shows I watched enough times that I was about to be annoyed, frustrated or infuriated by them. Some of the shows are just plain awful, but some are shows that have the potential to be so much more and yet squander that potential.
And congratulations to perennial Bottom 10 favorite "Criminal Minds": I only watched a single episode this year, the backdoor pilot for the spinoff. It was really bad. But only watching one episode isn't enough for inclusion on this list...
"Sons of Tucson"
"The Marriage Ref"
"Rizzoli & Isles"
"Pretty Little Liars"
