Criminal Minds is a CBS show about profilers for the FBI's Behavioral Analysis Unit. It has been airing since 2005 and is currently in it's 5th season. I did not know about this show when it first came out and only recently discovered it. I really liked it and that prompted me to want to catch up on previous seasons. Here are two links to help you catch up as well.
