There are still good dramas on the BBC, but you can tell they've had to run many repeats to free up money for their production elsewhere. That's not a total disaster because there was a tendency to produce something and it was ages until it saw the light of day again.I reckon the Sewing Bee is likely to survive because it fits into the lower-cost production slot like Bake-Off and the interior design programmes.
Since the general attack on the BBC started some years back, which altered the charter, they've been digging up some old gems and running them in the afternoon (so that I can't see them). Like The Pallisers, Parkinson's and Wogan's best interviews, sitcoms like Two-Up, Two-Down and Just Good Friends. I was hoping they would re-run the Onedin Line, but it seems they have some misguided plan to re-make it!
I have to say I think the general public is partially to blame for the direction of the BBC. BBC2 stopped most of its proper educational output after studies in trends and viewing habits (and a wrong-headed decision about the internet). People seem to want more entertainment and less information and the BBC has to now compete with bottom denominator broadcasters like Murdoch's SKY, and also quality output from HBO and AMC in the U.S.
