Miss Sloane ★★★

Chastain is fantastic in ice cold mode, but the middling screenplay can't match her. The third act, and especially the last 15 minutes or so, is so insanely convoluted that the entire film unravels in a risible tangle of ludicrous plot machinations. The blaring score is another particular irritant, often making it tough to hear the dialogue, so keen is it to tell us we're watching a significant moment.
