Before 'Criminal Minds,' most police procedurals focused on the "who" bit of "whodunit." But, when the Mandy Patinkin CBS series debuted in 2005, it was one of the first to ask not only "who," but "why." What resulted was a series that lasted over 300 episodes and 15 years — even if all of its cast didn't. Patinkin included, who called his two seasons on the show his "biggest mistake."You, like the FBI's Behavioral Analysis Unit, might wonder... why? Our latest episode gets into it all, delving into the history and impact of 'Criminal Minds.' During the episode, we learn about Matthew Gray Gubler's surprising pre-'Criminal Minds' career, which gigantic series it actually beat in the ratings, and how Kirsten Vangsness lasted more than just the one episode she was cast for. Plus: 'Criminal Minds's 'Friends' tie-in, and Thomas Gibson's splash in a hot tub. So grab your private jets (wheels up in five, btw) and enjoy the story of 'Criminal Minds'!
