What does a studio do after they're released every season of a TV show? Why release a complete series set of course! This week we're featuring reviews of the latest series boxed sets including:  Fraggle Rock: The Complete Series Collection - a fantastic show in an attractive binder with some fantastic bonus features; The Cosby Show: 25th Anniversary Commemorative Edition - one of the great TV sitcoms of all time, period, no argument, and it should be in the library of any serious television comedy fan; and The Complete Monty Python's Flying Circus - inarguably the most influential comedy troupe, and probably comedy television program, of the past 40 years. Get this set. Other shows recently reviewed include:  Speed Racer - The Complete Classic Series Collection, The 4400: The Complete Series, and Mr. Bean: The Ultimate Collection.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
