I'd suggest that most of 'everything the BBC produces' is utter rubbish. Most documentaries/factuals/dramas are made outside of the BBC. Probably the News content but that's getting trivialised and is almost like children's Newsround was a couple of decades ago.
Best thing I'm watching on BBC is What we do in the Shadows, but again, not the BBC's own work, an American import.
The BBC gets nearly £4 billion every year from us..
