TV on DVD remains very popular with more and more favorites being released. New TV reviews include:  Doctor Who: The Complete Fourth Series DVD review - the best season yet, and it ends so spectacularly that the final episode is, in its own fabulous way, an enormous "thank you" to everyone who helped not only revive the franchise; Newsradio: The Complete Series - one of the best sitcoms from the 1990s, consistently smart and funny and with one of the most talented ensemble casts of the day; and Dark Shadows: The Beginning, Vol. 6 - an endearing entertainment that defies the standards to stand the test of time. Other shows recently reviewed include:  The Paradise Lost Collection, The Universe Collector's Set, and How I Met Your Mother - Season Three.  Want more?  Check out all of the TV on DVD reviews in the DVDTalk database.
