Writer-director Riley Stearns (Faults) is a dark-comedy talent to watch. His latest film, focused on a timid accountant (Jesse Eisenberg) who takes up karate after he is mugged by a biker gang, stabs at the heart of traditional masculinity: What does it mean to “be a man” anyway? Beyond examining the question, this satire flays it wide open, exposing a netherworld at the karate studio that invites comparisons to Fight Club and Full Metal Jacket, with a shot of modern urgency. The karate instructor (Alessando Nivola) runs a cult of aggression to which the protagonist quickly subscribes. The chance to fight to the top of a new hierarchy, and look down on a less violent man (David Zellner) and the lone female of the group (Imogen Poots), constitutes a power trip too juicy to ignore. Analogous to the characters in filmmaker Yorgos Lanthimos’s satires, Stearns’s players speak in formal monotones, which pulls attention to their absurdist actions and the bizarre codes of the universe they inhabit. Powered by stilted interactions and an undercurrent of bloodlust, this society is at once strange and familiar in its uncomfortable parallels to reality.
