Miss Sloane: John Madden’s film may be the dream of people who criticize the political system; but it is, before that, a whip-smart, entertaining ride. The narrative is as intricate as it is unreal, but it makes one wonder, in any case. At its center is Jessica Chastain making the best use of her stern, cold beauty (assisted by the very well-chose costumes of Georgina Yarhi) in a great performance; she projects flawlessly the intelligence, cynicism and intensity of her character (which is a perfect example of an unpleasant character that is impossible to turn away from). The rest of the cast is very strong as well, in particular Gugu Mbatha-Raw; everyone handles the lightning quick dialogue very well. Sebastian Blenkov’s cold, steely images match the tone of the story.
