I never tire of watching this excellent piece of television. Every episode, and I've seen them all, has something new and never becomes boring. The characters are fantastic and the acting is first class. I love the style of humour and the references of things "still to come". The occasional inclusion of real life famous characters of the time is both intriguing and at times funny. I really hope it goes on for another 200 or so episodes. Best drama on TV by miles.
