All we learn from Miss Sloane is what we already knew: D.C. is debased, but Hollywood is obtuse, and this country needs a better class of political fantasy.

Miss Sloane has a narrative momentum that is hard to wholly resist. It's absurd. But it's never boring.

Hard to root for but mesmerising to watch, Sloane is expertly portrayed by Chastain in this dialogue-heavy lobbyist thriller that should please fans of both actor and genre.

Raging rapids of shouted Second Amendment vitriol, media spin, dirty deeds, competing poisons, political traps, double crosses, and triple crosses flow to create the outrageous twists and turns of “Miss Sloane."
