3 major themes

Mon Mon Mon Monsters Meaning: Themes & Message Explained

What is Mon Mon Mon Monsters (2017) really about? The emotional, social and philosophical themes the film keeps returning to, its symbolism and the message beneath the surface.

  • Bullying

    A core driver of the plot, the bullying circle wields social status to isolate Lin and coerce him into a cruel dynamic. The bullies systematically humiliate others, exploit the elderly, and weaponize fear to maintain control. The story shows how power, group think, and peer pressure can erode empathy and turn victims into accomplices. The escalating cruelty culminates in catastrophic consequences that ripple through the school.

  • Monstrosity and humanity

    The two ghouls are revealed to be former humans, victims of dark magic whose monstrous forms blur the line between human and monster. Lin’s empathy toward the younger ghoul contrasts with the bullies’ dehumanization, challenging who is considered monstrous. The film uses the creature’s biology and vulnerability to examine how fear and prejudice shape moral judgments. The monsters’ humanity is revealed through their kinship and tragic end.

  • Violence and its consequences

    Violence compounds violence: the teacher’s death and the ghoul’s rampage expose the consequences of cruelty. Lin’s eventual decision to poison the class and his own demise symbolize the self-perpetuating cycle of harm. The film closes with a grim reflection on how cruelty breeds catastrophe, transforming victims into agents of destruction themselves.
