Merlí. Sapere Aude is a Spanish-language series that turns teaching into theater. The show follows Merlí Bernabeu, a philosophy professor at Barcelona’s Liceu Institute, as he navigates a world of teenage angst, academic politics, and his own complicated past. The series is the second season of a show that began with Merlí, and it picks up where the first left off, with Merlí still grappling with the consequences of his actions while trying to help his students find meaning in their lives.
The title itself is a Latin phrase meaning “Dare to Know.” It fits a show about education as a kind of rebellion against ignorance, and the series treats its subject with genuine respect. Merlí is not a saintly figure; he is a flawed man who has made mistakes, and the show does not pretend otherwise. That honesty is what makes him compelling.
Merlí’s Classroom
Merlí teaches philosophy to a group of high school students who are lost, angry, or both. He sees their problems as philosophical questions in disguise, and he approaches them with the same rigor he applies to Socrates or Nietzsche. The classroom scenes are the show’s engine, and they are often sharp and funny. Students argue, interrupt, and crack jokes, and Merlí lets them, sometimes redirecting the conversation with a single question that cuts through the noise.
The show also takes its setting seriously. The Liceu Institute is a private school in Barcelona, and the series uses its campus as a character. The marble halls, the ivy-covered walls, and the students’ privilege all shape the stories. Merlí’s students come from wealthy families, and the show does not ignore how their backgrounds affect their decisions. One plotline involves a student whose father is a powerful businessman, and the series explores how wealth can isolate a young person even as it opens doors.
The Central Mystery
The central mystery of Merlí. Sapere Aude revolves around a student who goes missing after a fight with her boyfriend. Merlí becomes involved in the investigation, and the case forces him to confront his own past. The show builds tension slowly, weaving together threads from Merlí’s history with the present-day drama of the search. The result is a slow-burning thriller that rewards patience.
The investigation is handled with care. The show does not rush to conclusions, and it allows the audience to feel the weight of the situation alongside the characters. There are moments of dread, and there are moments of quiet hope, as Merlí works to understand what happened to the missing student and why. The case is not solved quickly, and the show trusts its audience to sit with uncertainty.
Merlí’s Own Story
Merlí has a secret. His past is dark, and the show spends time exploring it. He is a man who has done terrible things, and he carries that burden with him everywhere he goes. The show does not shy away from the ugliness of his history, but it also shows his growth. He is trying to be a better person, and the show tracks that struggle without ever letting him off the hook.
His relationship with his ex-wife is a major subplot. They have a son together, and Merlí’s behavior toward her is often cruel. He calls her names, he dismisses her feelings, and he treats her as an inconvenience. The show does not excuse this, and it makes the audience uncomfortable. That discomfort is the point. The show wants viewers to see Merlí’s flaws clearly, and it does not soften them.
The Ensemble Cast
The supporting cast is strong. Merlí’s colleagues at the Liceu include a headmaster who is deeply conservative and a teacher who is passionate but unorthodox. These characters give Merlí room to be himself, and their interactions are often the show’s best scenes. The students are also well-drawn. Each one has a distinct personality, and the show gives them enough screen time to make their fates matter.
The show’s handling of its ensemble is notable. It does not reduce anyone to a stereotype, and it gives each character a moment to shine. Even minor figures get fully realized arcs, which keeps the story from feeling thin. The result is a show that feels populated, with people who live beyond the plot they are in.
Comparing the Seasons
| Season | Focus | Tone |
|---|---|---|
| Merlí | Merlí’s first year at the Liceu | Lighter, more focused on relationships |
| Merlí. Sapere Aude | The missing-student case and Merlí’s dark past | Darker, more complex |
The comparison is useful for understanding how the show has grown. The first season was a warm introduction to Merlí and his world, while the second is a darker, more mature exploration of his legacy. Both are excellent, but they serve different purposes.
What Works
The writing is sharp. The dialogue is clever without being showy, and the philosophical references are used to advance the story rather than to show off. The show understands that ideas are most interesting when they are applied to real people, and it never loses sight of that.
The direction is confident. The series knows when to linger on a shot and when to cut quickly. The cinematography is beautiful, capturing Barcelona in all its light and shadow. The show also handles its pacing well, balancing the slow burn of the missing-student case with faster, more immediate scenes involving Merlí’s personal life.
What Falls Short
The show is not perfect. Some of the subplots feel rushed, particularly those involving secondary characters. The show’s commitment to its central mystery means some threads get less attention than they deserve. Additionally, Merlí’s cruelty toward his ex-wife can be difficult to watch, and the show does not always justify the extent of his behavior.
The show also leans heavily on its setting. For audiences outside Spain, some cultural references may pass by without explanation. This is not a flaw per se, but it does mean the show is not always accessible to international viewers. However, the core themes of family, identity, and morality are universal, and they carry the story regardless of specific context.
The Verdict
Merlí. Sapere Aude is a strong follow-up to a beloved show. It deepens the world of the Liceu and gives Merlí a more complex arc. The missing-student case is gripping, and the show’s exploration of its central character is rewarding. It is not a perfect show, but it is a very good one.
The series holds a TMDB audience score of 8.2 out of 10, and that number feels earned. It is a show that respects its audience and its characters, and it pays off the investment of time it asks for. It is worth watching for anyone who enjoys smart, character-driven storytelling, and it stands as a reminder that teaching can be a noble profession, even when the teacher is far from noble himself.
