Second-guessing my own snobbery, I decided to skip the Republican debate last night and watch Gone Girl. It was bound, I figured, to be slickly entertaining at least. And for a while, it was. But Fincher eventually succumbs to the ugly vacuity of his source material, concocting a crude, incoherent misogyny instead of the zeitgeist-capturing femme fatale he must have intended. Another night possessed by bad politics.
