I would agree with that, poop. While all the other characters sort of orbit around Nancy, she's really just the anchor of a superb ensemble. I never thought I'd like Kevin Nealon this much. And Justin Kirk is a scream; it would be too easy to paint his character with too broad a brush, but he provides just enough restraint at just the right times.
There's an edge to this show that I think adds to it's appeal. You're never quite sure where they're going, and they're not afraid to mine dark situations for whatever levity they can wring out of 'em. Certainly worthy of 30 minutes a week of tube-time.
