Some great TV shows have made their way onto DVD this week including:  South Park: The Complete Twelfth Season - another excellent selection of episodes and Paramount/Comedy Central improves on the lack of extras that hampered previous releases by adding a few fun featurettes; Andy Richter Controls the Universe: The Complete Series - an odd, quirky, frequently hilarious little gem of a show, the smart writing and engaging cast always entertain; and Kennedy: The Complete Series this made-for-TV mini-series evocatively re-creates an unforgettable moment in American history. Other shows recently reviewed include:  Gym Teacher, Skins - Vol. 1, and WWE: The Best Of Saturday Night's Main Event.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
