Sex and the City started veering this way shortly after 9/11, when the glamor of Blahniks, Louboutins and the sparkly city itself–which once were mere charming backdrops to cunning parables about love, sex and friendship–became the true stars of the show.

If you happened to see the original 2012 hit, in which the hopelessly sweet and affable beefcake Channing Tatum played a successful male stripper in Tampa, Florida, who yearns for more from his life, you may remember how Steven Soderbergh managed to direct that flick with a combination of the muted realism he used in Sex, Lies and Videotape and Traffic and the populist streak of everyday working-class American hustle he brought to Erin Brockovich.
