UNTIL 'SIMPLE LIFE,' THAT IS: Seriously, how did "Arrested Development" get greenlighted? It is original, it has a great ensemble cast, and it beat the you-can't-be-funny-in-a-pilot curse. In short, everything the American "Coupling" was not. I'm going out on a limb and calling the "best new show" race over. So how long until Fox, which prematurely killed the last great new comedy, Judd Apatow's "Undeclared," starts running the episodes out of order, pulling the show for sweeps, and refusing to promo it? My advice is to watch it before it gets replaced by reruns of "Mr. Personality."
