There are so many procedural dramas on TV, from all the "Law & Order" shows to the many "CSI" spinoffs. But "Blue Bloods" is different. This CBS drama follows the Reagan family as they navigate the ups and downs of not only being deeply entrenched in the New York City justice system, but also the dramas that just come from being a family, as per CBS. There's Frank Reagan, played by Tom Selleck, who is the patriarch of the family and the police commissioner. Donnie Wahlberg brings Danny Reagan, an experienced detective, to life, while Bridget Moynahan portrays Erin Reagan, an assistant district attorney.
