The fourth series of Sex and the City is just as smart and sexy as ever, mixing caustic adult wit and sharply observed situation comedy on the mean streets of Manhattan, though this time the quartet of singleton city girls must endure even tougher combat in the unending war of love, sex and shopping. Carrie (Sarah Jessica Parker) finally seems to have found her ideal life partner when she is reunited with handsome craftsman Aidan. But can their relationship survive trial by cohabitation? Meanwhile Charlotte (Kristin Davis) seems to have both her dream Park Avenue apartment and a solution to her marital problems with Trey (Kyle MacLachlan), as well as conquering his fearsome mother. But when the subject of babies comes up everything starts to unravel for her, too. It's not just Charlotte having baby issues either: after what seems like an eternity of enforced sexual abstinence, Miranda (Cynthia Nixon) is horrified to discover she's pregnant. And as for the sultry Samantha (Kim Cattrall), she's on a quest for monogamy, first with an exotic lesbian artist then with a philandering businessman, with whom to her utter dismay she just might have fallen in love. --Mark Walker
