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.
