I first saw You Rang, M'lord over 15 years ago. My motivation was in fact Miss Cissy's picture in the TV program - of course I wanted to see anything with a lesbian character! But while I wasn't disappointed in Cissy, I grew fond of the whole household, masters and servants alike. I have since seen it dozens of times on TV, video and DVD.
I truly think You Rang, M'lord is a masterpiece of English sitcom. Firstly, it's a nice parody of the rigid social boundaries in British society ("No, Henry, you don't open the door. Mr. Twelvetrees opens the door. If he is not here, Ivy opens the door. If Ivy is not here, I open the door", lectures Mrs. Lipton.) However, the characters are more than just representatives of their respective social classes. They all have a full-fledged personality, a whole life outside the confines of the series (think of reports about Mabel's husband or visits to the Kitkat Club). Even relatively minor characters, like Lady Agatha, are three-dimensional. Every character is extremely funny and yet likable. The moment one would start to hate Alf or Miss Poppy, they immediately do something (and it might just be a glance or a smile) to win our sympathy back. Psychologically the whole series is perfectly realistic and logical. No wonder there're no 'goofs' listed about this series on IMDb. There aren't any.
I have seen other sitcoms by Jimmy Perry and David Croft, but this one exceeds all of them. The excellent acting contributes to this, too. I couldn't point out one actor over the others; they all do a brilliant job.
