Guillermo del Toro, known for his unparalleled creativity as a writer and director, continues to make waves in the horror genre. While fans eagerly anticipate his upcoming Netflix release of Frankenstein on November 7, there is another compelling Guillermo del Toro horror series currently streaming on Hulu that deserves much more attention. The Strain, co-created years ago by del Toro, offers a dark and intense narrative blending horror, science fiction, and apocalyptic thriller elements.
An Overview of The Strain’s Storyline
One of Guillermo del Toro’s lesser-known projects is the television adaptation of The Strain Trilogy, a book series he co-wrote with Chuck Hogan in 2009. This trilogy was transformed into a TV show aired on FX from 2014 to 2017, with del Toro co-writing and directing the pilot episode. The series is notable for its unapologetically graphic and disturbing tone, shaped further by the involvement of showrunner Carlton Cuse, known for his work on Lost and Bates Motel. Together, the team crafted a horror series that faithfully followed the novels’ intense atmosphere but did not receive widespread recognition during its run.
The show centers on a viral outbreak in New York City linked to a mysterious death aboard a flight landing at JFK Airport. When the ground crew finds the passengers onboard dead and unresponsive, epidemiologist Dr. Ephraim Goodweather (played by Corey Stoll) is enlisted to investigate. His initial assumption of a serious viral infection soon unravels into something far more sinister: a parasitic vampiric affliction transmitted by worm-like creatures.

The infected do not resemble typical vampires; these strigoi vary from zombie-like entities to stealthy predators capable of passing as human. They possess supernatural speed and operate under the control of an ancient vampire Master who aspires to take over the world. Ephraim joins forces with a Holocaust survivor and professor, Abraham Setrakian (David Bradley), whose dark past and knowledge of the Master become vital, as well as a tough Ukrainian exterminator, Vasiliy Fet (Kevin Durand), who applies his unique pest control skills to the vampire threat.
The Strain’s Blend of Horror and Apocalyptic Tension
The series distinguishes itself by melding horror with apocalyptic sci-fi. The spreading virus evokes a city-wide catastrophe, heightening the stakes not only through graphic terror but also a suffocating sense of dread. The show’s horrifying imagery, such as parasitic worms emerging from the human body and grotesque vampire attacks involving tongues that shoot out like weapons, pushes boundaries of body horror rarely seen on television. These unsettling scenes were so intense that initial FX promotional materials featuring a worm protruding from a woman’s eye were withdrawn due to public discomfort.
Besides its visceral content, The Strain also incorporates elements of historical fiction. The background of vampirism ties into previous eras, enriching the mythology beyond cliché vampire tropes. As the characters battle the growing vampire menace, the show shifts toward adrenaline-pumping action sequences that inject urgency and tension into the narrative. Its Gothic undertones and refusal to romanticize its monsters elevate the series beyond typical vampire stories, evoking a grim and ruthless atmosphere that is as chilling as it is captivating.
Strong Acting Anchors the Series
Despite its fantastical horror premise, The Strain remains grounded through solid performances from a talented cast. Corey Stoll portrays Ephraim Goodweather with a blend of scientific skepticism and growing horror, making his character relatable amid extraordinary circumstances. Veteran actor David Bradley delivers a compelling portrayal of Abraham Setrakian, imbuing his role with haunted gravitas and essential wisdom that drives much of the story’s suspense. Kevin Durand shines as Vasiliy Fet, the no-nonsense exterminator whose physicality and street-smart presence add depth and rough charm to the ensemble.
The show also includes memorable appearances from respected actors such as Sean Astin, Samantha Mathis, and Regina King, each enhancing the story’s complexity and appeal. Despite completing its storyline in four seasons, The Strain never achieved the level of fame enjoyed by other horror vampire series like True Blood or AMC’s Interview with the Vampire. It quietly built a devoted following, drawn to its intense narrative and fearless horror.
Why The Strain Deserves More Recognition and What Awaits Fans Next
Although it ended in 2017, The Strain remains an exceptional exhibit of Guillermo del Toro’s unique approach to horror, offering a perfect blend of visceral scares and thoughtful storytelling. The series is not for viewers sensitive to graphic violence or disturbing images, but for those who appreciate intense horror and apocalyptic concerns, it offers a gripping viewing experience. Watching The Strain now can serve as a fitting tribute to del Toro’s talent while generating anticipation for his forthcoming Frankenstein adaptation, promising more dark, masterfully crafted storytelling.
The Strain is currently available to stream on Hulu in the United States, making it accessible for those looking to dive into this underrated corner of del Toro’s oeuvre in the meantime.
