Peculiarly, and probably pathetically, I was rather excited about the idea of a remake of Upstairs, Downstairs. (The remake's title is sans the comma. Which ought to have been a bad sign, and was.)
It's silly, really. Can you be nostalgic about a remake of a series which was about nostalgia, even in 1971 when it was first made? Not my nostalgia, of course.
You could only be nostalgic about the days of having swags of servants to plump your cushions and pour your tea if you'd had such a lifestyle, and then you would have had to be born a long time before 1971.
The thing about nostalgia telly, and it's why Downton Abbey has been such a hit, is that you can imagine what it was like to flutter about in lovely gowns having your cushions plumped and so on.
But the nostalgia attached to the idea of Upstairs, Downstairs, (the comma-ed version) is nostalgia for something else altogether: a simpler time which has nothing to do with the period the series was set in, from 1903 to 1930, but for your own simpler times, before video recorders, let alone MySky, and all of those channels.
