It's that opening song after the intro, the way it ends, and that "dut done" sound during the show that makes it so enduring to want to watch despite you've seen every episode ten times. I can't believe you didn't catch onto Criminal Intent until later, loved that show, but I've always been draw to crime drama where the brains instance of interviewing potential suspects wins out. I was big on the Forensic Files, and from the desk of Dale Hinman, a female profiler, true life cases. I ditched cable awhile ago, always fell to sleep trying to watch it, when I started falling asleep during Dateline, I knew I was wasting my money but I admit it is the only show I miss watching. I got into watching that FBI profiler drama for a couple of years, can't recall the name of it, until it started getting to easy and absurd. I will always pick a crime drama or bad ass chick flick over much of anything else.
