Netflix's The Final Problem is a Spanish mystery thriller set against the elegant but unsettling backdrop of 1959. The limited series arrived on Netflix on September 25, 2026, adapting Arturo Pérez-Reverte's bestselling novel of the same name. Its central idea is particularly intriguing: an aging actor who once played Sherlock Holmes on screen is forced to investigate a real murder when a storm traps him and a group of other people inside an isolated hotel.
That premise gives The Final Problem Netflix review an unusual angle. This is not another Sherlock Holmes adaptation. Instead, it asks what happens when an actor who spent years pretending to be the world's greatest detective suddenly has to solve a genuine crime.
José Coronado leads the series as Benjamin Basil, with MarÃa Valverde, Martiño Rivas and Maribel Verdú among the principal cast. The show is directed by Félix Viscarret and combines period drama, crime mystery and classic whodunit elements.

The Final Problem Story and Plot
The story begins in the spring of 1959, when a violent storm isolates thirteen people on a small island near Mallorca. They are staying at a secluded hotel, but the peaceful atmosphere quickly disappears when English tourist Elisa Mander is found dead.
At first, the death appears to be suicide. However, circumstances surrounding the incident raise doubts, turning the situation into a murder investigation. Because nobody can easily leave the island and outside help is delayed, suspicion falls on practically everyone inside the hotel.
Benjamin Basil becomes the unlikely investigator. He is not a professional detective. His unusual qualification is that he once portrayed Sherlock Holmes in films.
That detail is the heart of the series. Basil has spent years studying and performing the behavior of a fictional detective, and now the people around him expect those skills to work in real life.
He is joined in the investigation by Francisco Foxá, a young thriller writer. Together, they begin examining the guests, their relationships and the increasingly suspicious events taking place inside the hotel.
The isolated setting creates the classic closed-circle mystery structure: the killer is presumably already among the people trapped there, meaning every conversation, secret and contradiction becomes potentially important.
Cast and Characters
José Coronado as Benjamin Basil
José Coronado plays Benjamin Basil, the retired actor at the center of the mystery. Basil's history of portraying Sherlock Holmes makes him different from a conventional detective protagonist.
The character is interesting because his reputation comes from playing a fictional investigator rather than actually being one. That creates a natural tension between Basil's public image and his real abilities.
MarÃa Valverde as Adela Figueroa
MarÃa Valverde plays Adela Figueroa, one of the important figures among the hotel guests. Her character becomes part of the mystery surrounding the people trapped on the island.
Martiño Rivas as Francisco Foxá
Martiño Rivas portrays Francisco Foxá, a young thriller writer who becomes closely involved with Basil's investigation.
Foxá provides another perspective on the mystery because, like Basil, he understands the conventions of detective stories while still being an outsider to an actual investigation.
Maribel Verdú as Mrs. Raquel Ausländer
Maribel Verdú plays Mrs. Raquel Ausländer, the hotel manager. In a mystery where the staff and guests can all become suspects, her position naturally makes her an important part of the story.
Other cast members include Gonzalo de Castro, Cristina Kovani, José Condessa, Pepón Nieto, Daniel HolguÃn, Michael Stobbe and Yaiza Guimaré.
Performance and Acting
The strongest attraction in the cast is José Coronado's central role as Basil. The character allows the series to play with the contrast between a performer and the fictional detective persona he became famous for portraying.
Early reviews have not been completely unanimous. One review praised Coronado's presence and the basic actor-as-detective idea but felt that the mystery itself was too familiar. Another early Spanish review described the series as an appealing traditional mystery for viewers who enjoy classic detective fiction.
MarÃa Valverde has also received attention in early criticism, particularly for bringing a controlled and mysterious quality to Adela Figueroa.
Because the series has only just been released, audience opinion is still developing.
Direction and Screenplay
Félix Viscarret directs The Final Problem, while the screenplay is credited to Marisol Ferré, Alberto MacÃas and Carlos Molinero, with Arturo Pérez-Reverte credited as the novel's author.
The writing has an obvious challenge: the series has to make its own detective story work while also using the idea of a character who became famous by playing Sherlock Holmes.
That meta-fictional concept is arguably the most distinctive part of the setup. However, early critical reaction suggests that the series sometimes relies heavily on traditional whodunit conventions rather than constantly reinventing them. One review specifically criticized its slow pace and felt that the mystery did not generate enough momentum.
For viewers who prefer slow-burn mysteries, that measured approach may be appealing. Those expecting a fast, twist-heavy thriller may find the pace more restrained.
Genre and Major Themes
The Final Problem combines several genres:
- Crime
- Mystery
- Thriller
- Period drama
- Historical drama
- Whodunit
Netflix itself categorizes the series as a Spanish drama, mystery, crime thriller and book adaptation.
The central themes include identity, deception, reputation and the difference between fiction and reality.
Basil's situation is particularly interesting because his professional identity is based on pretending to be Sherlock Holmes. The murder forces him to discover whether the skills he performed on screen can actually help him when the stakes are real.
The isolated hotel also creates another important theme: trust. When nobody can leave and everyone has something to hide, even innocent behavior can look suspicious.
Music, Cinematography and Visual Style
The period setting is an important part of the series' atmosphere. The story takes place in 1959, and the hotel becomes the visual center of the mystery.
The production uses formal costumes, an isolated luxury-hotel environment and stormy surroundings to create the feeling of a classic European murder mystery.
The visual approach is less about spectacular action and more about atmosphere, enclosed spaces, suspicious conversations and the gradual discovery of clues.

The Final Problem Trailer Review
The official trailer immediately establishes the central mystery: an isolated hotel, a suspicious death and a group of people who cannot simply leave.
The trailer introduces Basil as a retired actor who once played Sherlock Holmes and is unexpectedly pushed into investigating the murder. It also highlights Adela Figueroa, Foxá and the hotel manager while emphasizing the growing suspicion among the guests.
Rather than presenting itself as an action-heavy thriller, the trailer sells the series through mystery, atmosphere and character suspicion.
The strongest hook remains Basil himself. Seeing a former Sherlock Holmes actor investigate a real murder gives the series a playful connection to detective fiction without making it a direct Sherlock Holmes story.
Is The Final Problem Available on Netflix?

Is The Final Problem available in India?
Yes. The series is available through Netflix in India following its September 25 release.
What Works in The Final Problem
1. The actor-as-detective idea
Basil's background gives the familiar murder mystery a different starting point. He has played Sherlock Holmes, but he is not actually Holmes.
2. The closed-location mystery
An isolated hotel surrounded by a storm is an effective environment for a whodunit. The limited number of suspects naturally encourages viewers to study every character.
3. Strong period atmosphere
The 1959 setting gives the story a distinctive identity and separates it from contemporary crime thrillers.
4. José Coronado's central performance
Early reviews have generally recognized Coronado as one of the series' key strengths, even when their assessment of the mystery itself has been more mixed.
5. Suitable for mystery fans
Viewers who enjoy traditional detective stories, secretive characters and slow-burn investigations may find the setup appealing.
What May Not Work
The biggest potential weakness is pace.
One early review criticized the series for moving too slowly and argued that the suspense does not always build as strongly as the premise promises.
Another issue is familiarity. The isolated-location murder mystery is a well-established format, so viewers who have watched many Agatha Christie-style whodunits may recognize some of its basic ingredients.
The series' most original concept is Basil's history as a Sherlock Holmes actor. If a viewer expects that idea to become a major source of humor or deeper character development, the actual mystery may feel more conventional than expected.
Who Should Watch The Final Problem?
The Final Problem is likely to appeal most to viewers who enjoy:
- Classic whodunit mysteries
- Slow-burn crime thrillers
- Agatha Christie-style closed-room stories
- Spanish-language dramas
- Period mysteries
- Sherlock Holmes-inspired stories
- Murder mysteries with multiple suspects
- Netflix limited series
It may be less suitable for viewers looking for constant action, rapid pacing or a conventional Sherlock Holmes adaptation.
The Final Problem Review: Final Verdict
The Final Problem has an appealing central idea: what if an actor famous for playing Sherlock Holmes had to solve a genuine murder?
That premise, combined with a storm-isolated hotel, thirteen trapped people and a suspicious death, creates a strong foundation for a traditional mystery. José Coronado gives the series a compelling central presence, while the period setting adds atmosphere.
However, the early critical response suggests that the execution may feel more conventional than the premise initially promises. One review gave it 2/5 and criticized its slow pacing, while another early review gave it 3.5/5 and highlighted its classic mystery appeal.
So, rather than presenting it as a universally acclaimed thriller, it is more accurate to describe The Final Problem as a traditional Spanish mystery with an unusual Sherlock Holmes connection.
