Boy Kills World is a violent and gory action-thriller that is heavily inspired by video games. The film follows Boy, a trained assassin who must take down a totalitarian figurehead. Boy’s journey is filled with surreal and slapstick humor, but the film’s over-the-top violence and relentless voice-over narration may be too much for some viewers. The film is a litmus test for fans of video game movies, and its success will depend on viewers’ ability to embrace its absurdities.
