Some great TV shows have made their way onto DVD this week including: Terminator: The Sarah Connor Chronicles - Season Two [another review, Blu-ray review #1, and Blu-ray review #2] - as these rave reviews attest, this set is one of the better stretches of television in recent memory; The Mentalist: The Complete First Season - an off kilter police procedural that is a joy to watch; and It's Always Sunny in Philadelphia: The Complete Fourth Season - another thirteen episodes of inspired offensiveness. Other shows recently reviewed include:  An Old Fashioned Thanksgiving, The No. 1 Ladies' Detective Agency: The Complete First Season and Life on Mars: The Complete Series.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
