If you look at some shows that have an ugly feel to them, or a nihilistic sort of feel to them, you'll usually find a group of cynical, unhappy, miserable people behind the production. If you see a show that's rather boring, or a cookie-cutter factory show, you'll usually find some pretty uninteresting, boring people behind it.
Everyone always wants to talk about 'True Blood' and 'Battlestar Galactica' - no one's even interested in 'Durham County.' It blew my mind when I came to Canada and no one asked me about the show. So many people didn't even know about it. They didn't even know it was on the air! It's very curious to me.
