Ever hear of horrible crime commited and wonder "What were they thinking?", or "What could bring a person to do such a thing?!"....well this show answers those questions in a very slick, very captivating way. The characters are believable as they go about the business of not only solving the crime, but explaining, however brutal, why it happened. This show is not for the timid or easily shocked nor is it for the very young. The whole psychology behind some of the worst crimes against humanity is played out in every episode in not so much a visually graphic way, but moreso in the dialog and even more in what is not said, as your mind puts together the string of events that led up to the "unsub" as they are called in the show, meaning the unknown subject that did the horrible deed. Just as CSI goes into the physical science of solving crimes, this show goes into the psychology of solving crimes. What could make a person do such a thing? Watch this show and find out.
