My sarcasm aside, one of the reasons I suspect HHN shows have been so well received (HNF, B&T, Jack) is that they don't have to be all things to all people. No worrying if it's too adult for the kids, or that the humor is too Americanized for an international audience. In a weird way, DCL shows are similar -- knowing your audience is 90% hard-core pixie dusters, you can cater to their tastes more directly.
