The biggest problem with television as an art form right now is that it gives us too many new shows but too few new stories. Doctors. Lawyers. Cops. Wild teens. Families with Neanderthal husbands, harried wives, and a few cute kids. Series set in outer space or in a fantasy realm, where the political conflicts echo our own. There's comfort in familiarity, to be sure. But it's a rare pleasure, these days, to encounter a premise that feels genuinely original.
