Some great TV shows have made their way onto DVD this week including: The Bob Newhart Show: The Complete Series - the astonishingly consistent performances, writing, and direction make this iconic show a must-own for comedy fans; I Spy: The Complete Series - Bill Cosby and Robert Culp's performances are the definition of chemistry, and there are a number of genuine gems amongst these 82 hours of spy adventures; and Bret Maverick: The Complete Series - though short-lived, this show is an awfully fun series, a perfect companion set to both the original Maverick and as an almost-continuation, The Rockford Files. Other shows recently reviewed include:  Seduced and Abandoned, Laverne & Shirley: Eighth & Final Season, and Dead Like Me: The Complete Series.  Want more?  Check out all of the TV on DVD reviews in the DVD Talk database.
