I find much tv not particularly interesting these days; mainly this is because it's cheap programming (pick up a camera and follow someone), spun out (hour programmes that could be done in 20 minutes were it not for padding), or celebrity-style.
Having said this, there were a batch of programmes I thought I'd have a look at on Friday night BBC. One was "History of Christianity". The art in the camera work and direction in the first episode was stunning (so good it distracted from the other content!) One programme I was glad I'd watched, and didn't feel had wasted my time.
As for nostalgia, Roger, we're spending the last half-hour of every evening watching a series of programmes on steam trains, produced in the mid 1980s. Wonderful!
