What series do you think is/are worth the money on DVD, for whatever reason? There are at least three that are that for me: --The Streets of San Francisco: I recently finished CBS' all-in-one DVD of this 1972-77 ABC police/detective series, and to me, while Michael Douglas and Richard Hatch had equal parts to play in making it successful, I think the main man worth your disc dollar for this series is the late, great Karl Malden (as Lt. Mike Stone); from what I've read, Karl was so successful here that he translated his Stone character into those equally successful and quite well-remembered American Express Travelers' Checks commercials ("American Express Travelers' Checks: don't leave home without them!"). --Barney Miller: Hal Linden's portrayal of the titular fictional police captain in NYC in this 1975-82 ABC police comedy is worth the money here because he played the captain of a police force that was more about the patience and paperwork and humor than practically any other televised police squad, comedy or drama. Not just that, but its title track and title sequence were very well done for the time. --The Bob Newhart Show: Bob Newhart's role of more-or-less even-tempered Chicago psychologist Dr. Bob Hartley in this 1972-78 CBS comedy is, IMO, more worth the money on DVD than his later role of Vermont innkeeper Dick Loudon on Newhart from 1982-90 on the same network; it's because Dr. Bob Hartley, for reasons I cannot find the words to explain, is far more believable and enjoyable to me than Dick Loudon. Which one(s) do you think is/are/have been worth your money?
