If you are looking for an anime that trades spectacle and superpowers for intense, grounded psychological dread, Monster is the definitive answer. This series, based on the brilliant manga by Naoki Urasawa, operates like a prestige cable drama—it’s mature, complex, and respects the viewer’s intelligence.
The brilliance of Monster lies in its central question: What is the worth of a single human life? And what responsibility does a savior bear for the evil they save? This moral depth is what elevates Monster far above a simple murder mystery.

Plot Overview: The Moral Quandary of Dr. Tenma
The story begins in 1986 Germany, centering on Dr. Kenzo Tenma, a brilliant Japanese neurosurgeon working in Düsseldorf. Tenma is forced to make a life-altering moral choice: save the life of the critically wounded mayor, or save a young boy who was rushed in minutes later. Tenma, valuing all life equally, chooses the boy, Johan Liebert, over the mayor due to medical priority.
This moral decision ruins Tenma’s career, but things turn sinister nine years later when it’s revealed that Johan grew up to be a charismatic, nihilistic serial killer. Tenma feels responsible for releasing the “monster” onto the world and dedicates his life to hunting him down to correct his past choice. The hunt takes Tenma across Europe, forcing him to confront the dark history of the Cold War and the true origin of the Monster.
Character Deep Dive: The Two Sides of Humanity
The core relationship between the protagonist and antagonist defines the quality of Monster.
- Dr. Kenzo Tenma: He is the ultimate moral protagonist—a true idealist burdened by guilt. His transformation is not about gaining power, but about struggling to retain his humanity and ethics while pursuing the most evil person he has ever encountered.
- Johan Liebert: Johan is perhaps one of the most terrifying antagonists in fiction. He is not motivated by money or physical conquest, but by the desire to demonstrate the emptiness and nothingness of life. His influence, his ability to manipulate people into self-destructing, and his unsettling lack of identity make him the true Monster.
Thematic Exploration: Identity, Nihilism, and the Nature of the Monster
Monster uses its detective-thriller framework to explore profound, philosophical questions.
- Identity and Names: The story heavily investigates how names and external labels shape—or fail to shape—identity. Johan’s identity is fluid and deliberately erased, symbolizing how the true monster can be anyone.
- Moral Responsibility: The series constantly questions the responsibility of individuals for the greater evils in the world. Is Tenma responsible? Are the doctors who performed experiments responsible? The story refuses to offer easy answers.
- The Legacy of Trauma: Much of the backstory revolves around the dark history of communist Europe and psychological experiments on children, highlighting how generational trauma and political systems can breed true evil.
Technical Review: Pacing, Realism, and Atmosphere
The technical decisions made in the anime perfectly capture the tone of Naoki Urasawa’s Monster.
- Pacing and Realism: The series is a slow burn. The pace is deliberately measured, focusing on police work, political conspiracies, and long, investigative dialogues over action. This commitment to realism makes the moments of horror and violence all the more shocking.
- Atmosphere: The use of European locations (Germany, the Czech Republic) is critical. The setting provides a dreary, realistic backdrop that contrasts with the fantastical scale of the conspiracy. The atmosphere of constant paranoia and dread is palpable throughout Monster.
Narrative Structure: The European Road Trip Detective Story
The structure of Monster is unique in anime, functioning much like a classic road-trip thriller. Tenma is constantly on the move, chasing Johan, which allows the narrative to introduce a huge array of secondary characters—police officers, former assassins, criminal lowlifes—each of whom contributes a small piece to the massive puzzle of Johan’s past and present activities. This expansive web of interconnected stories makes Monster feel vast and meticulously planned.
Critical Consensus: Strengths and the Deliberate Pace of Monster
My final assessment of this landmark series:
- Most Liked Aspects: The profound philosophical depth; the sheer genius of Naoki Urasawa’s long-term plotting; the chilling antagonist (Johan); and the series’ commitment to a realistic, grounded aesthetic.
- Improvable/Criticized Aspects: The deliberate pacing, while crucial to the atmosphere, can be a major hurdle for viewers accustomed to rapid, action-driven storytelling. The length (74 episodes) also requires commitment, but every episode is necessary to unfold the vast conspiracy of Monster.
Overall Score
For its moral complexity, masterful plotting, and mature psychological depth:
9.9 / 10
