Man, you don't know what you're missing. I'm an American, and I download so many BBC programs that I almost feel as if I should pay into the TV fund in Britain. Along with Doctor Who and several excellent Sci-Fi series, the BBC is also an endless source for fascinating documentaries: The Power of Nightmares, The Century of the Self, Tetris: From Russia With Love, Mortgaged to the Yanks, etc. Then there's excellent adaptions of classic novels and probably the best news programs in the English-speaking world.
Now compare that to crap like Will and Grace, Everyone Loves Raymond, and the typical garbage you find on network tv in America. I'll take the BBC any day.
