I heard repeatedly from friends and family that this show was interesting. However, the description of "it's a show about two U.S. Marshalls that work in witness protection," doesn't really grasp my attention. Then I found the dvds at the library and figured I'd give it a shot. The series was already finished with its second season by the time I started watching it. So, my impression. The reason to watch this show is mostly due to its characters. I think the plot could be about detectives, security guards, or sheriffs, but with Mary and Marshall as the main characters (and partners), the show would still be awesome. The writing is usually really good, though the screwed-up dynamic of Mary's family becomes irritating sometimes. I would recommend this show to anyone looking to watch some entertaining stories about crazy U.S. Marshalls and Witness Protection.
