It was Girls Night Out everywhere around the world last night. And there was a run on Cosmopolitans as well. After watching Sex and the City on opening night like all good card-carrying thirty- and forty-something women and gay men, we headed for the nearest bar and ordered what else but Cosmopolitans. Our rotund waiter was clueless as to why the dark pink drinks were unusually popular last night. And so began, drink in hand, a post-mortem on Sex and the City, the most hyped, most publicized, most fashionably self-conscious and most self-consciously fashionable movie of the year.
