It's not always easy choosing the "worst" show on a network like CBS, which has such a reliable stable of shows. However, of this fall's CBS lineup Gary Unmarried is my pick. I've tried to enjoy this sitcom, but I just can't. If I'm unlucky enough to end up watching it, by the time the 8PM CST hour rolls around I couldn't be more ready to switch to ABC's Modern Family or Fox's Glee.

I was not disappointed.
