Was reading the discussion about the Andy Griffith Show and Rodney commented on the change from Season 1 where Andy was a real "hick" and he and Barney were cousins. Later in the series Andy became a little wiser and no longer was related to Barney. That's what most people remember. I commented about M.A.S.H. In the first season Radar both smoked and drank. In later seasons he was the Nehi guy. That's what most people remember. How about the rest of you. What series have you gone back to watch and noticed major changes from the beginning of the show?
