There's a good reason some of the most iconic and acclaimed TV shows in history belong to the crime genre. These stories about compelling crooks operating on the wrong side of the law, righteous heroes trying to get them behind bars, and morally gray antiheroes doing their thing somewhere in between are among the most riveting stories that creators can tell through the small screen. When done right, a crime show isn't just interesting an entertaining, but edge-of-your-seat intense.
