Television should provoke debate - it's how a nation talks to itself.
Why do popular songs have so much power in your work?, asked the critic Michael Sragow.
Because I don't make the mistake that high-culture mongers do of assuming that because people like cheap art, their feelings are cheap, too. When people say, "Oh listen, they're playing our song," they don't mean "Our song, this little cheap, tinkling, syncopated piece of rubbish, is what we felt when we met." What they're saying is, "That song reminds us of that tremendous feeling we had when we met."
