A whopping 7.7 million viewers watched Sunday's mini-season finale of Sex and the City, during which Mikhail Baryshnikov was introduced as Carrie's (Sarah Jessica Parker) latest beau. (Note to Big: You've got nothing to worry about, dude.) That was the comedy's second most-watched episode ever. The show returns with eight final episodes in January. Meanwhile, Sex's impressive climax helped boost the debut of Carnivale, which drew 5.3 million viewers — HBO's best series bow to date.
