Combining the best elements of JAG and CSI, the CBS crime series NCIS focuses on an elite, independent unit of the U.S. Navy, which, in its pursuit of military-related criminal investigations, was answerable to no higher authority -- and thus, of course, was utterly impartial and incorruptible. Season 3 is now on DVD. Also on DVD: season 1 of The Drew Carey Show, The Odd Couple, One Day At A Time, WKRP In Cincinnati; and Kidnapped the complete series.
