When Blue goes off the air, that will suck. That's the only ABC show I watch as I cannot stand Madden so I don't watch Monday Night Football. Their other shows just don't interest me in the least.
Besides Blue, I watch Cold Case, the Law and Order shows (Criminal Intent is my favorite), the CSI shows, Without A Trace, and my usual documentaries on A&E like American Justice (my 2nd favorite show after Blue), City Confidential, Cold Case Files, and Investigative Reports.
I'll sometimes catch The Simpsons, but we just buy the seasons when they come out on DVD.
