With last weekend's ending to the bonus season of Sex and the City, HBO drew the curtain over a proverbial third act for its heroines. Once viewed as a frothy brew of so-fashionable-they're-hideous outfits and quips about a parade of stank-breathed, ball-scratching "toxic bachelors," the show got serious this season, pitching its characters into mid-drama crises where each of them received their karmic comeuppance -- be it a baby, a divorce, a breakup, or (horrors!) unexpected love.
