The director of Margin Call, All Is Lost, and A Most Violent Year was shaping up to be a main expertise for the nationwide arthouse circuit, but this film’s rah-rah dialogue, bilious shade-grading, and general Call of Duty feel solid unwelcome aspersions on his rep. It all helps make a particular person, even 1 amenable to the film’s standpoint on blackness and policing, come to feel like they’ve been performed.
