An uneven political thriller about a lobbyist switching sides over a bill imposing regulations on firearms, Miss Sloane aims for Aaron Sorkin levels of razor sharp dialogue but fails miserably. It’s social critiques feel forced, a side story involving Jake Lacy’s escort totally unnecessary, and its ending largely ludicrous – a Shyamalan-esque twist that attempts to turn the main character from ruthless to all-seeing oracle – but this is saved entirely by the incredible Jessica Chastain. In a career filled with phenomenal performances this is one of her very best – a commanding, imposing presence that somehow gives credibility to even the most illogical plot developments.
