Our CE review of the film read, "Bison is Mari Selvaraj’s most violent to date, and it is beautiful how the gore and bloodshed aren’t at the hands of the protagonist, but everywhere around him. It is a terrific exploration of the aftermath of violence and its unsettling consequences in the minds of the young and easily influenced."
