I find this show to have some of the most unique and interesting writing I've seen anywhere. I don't know how the scripts were developed, but my sense is that the actors were improvising and the scripts evolved out of that. It's hard to believe that all this could have come from the minds of one or two people, unless they are geniuses. I can't think of anything else I've seen that is so effective at giving the viewer a sense of truly being a "fly on the wall", getting actual glimpses of the lives real people live. Often, the scenes are utterly unpredictable, and the situations are hilarious, in a fresh, unforced way that doesn't feel "written" at all. It's really something special. A very intelligent show.
