“Wu Assassins” is a television series that understands what makes a fantasy action show work. It takes a simple premise — a young chef becomes the last in a line of supernatural warriors — and builds around it some of the best fight sequences ever put on screen. The series premiered on Netflix on August 8, 2019, with ten episodes. It follows Kai Jin, a wannabe chef in San Francisco’s Chinatown, as he reluctantly becomes the Wu Assassin after absorbing an amulet containing the collective essence of 1,000 monks who died together. The result is a show that leans hard on spectacle but rarely lets the spectacle cover up the story underneath.

The Premise
Kai Jin is not a man looking for trouble. He is a young chef trying to make a name for himself in the city’s restaurant scene. Then he encounters a mystical spirit, and suddenly he is carrying the power of 1,000 monks in an amulet. That power draws the attention of the Chinese Triad, who are pursuing deadly ancient powers known as the “Wu Xing.” Kai becomes the 1,000th and last in the line of Wu Assassins, tasked with recovering supernatural powers from five modern-day criminals threatening to destroy the world.
The setup is familiar territory for the genre, but the execution is sharp. The show wastes no time getting to the action. Within the first few episodes, Kai is fully vested with his abilities, and the series shifts from a character-driven drama into a full-on action adventure.
The Cast
The series stars Iko Uwais as Kai Jin. Byron Mann plays Uncle Six, Kai’s mentor and a key figure in the story. Katheryn Winnick appears as Christine Gavin, a homicide detective who partners with Kai to unravel the mystery. Lewis Tan, Lawrence Kao and Li Jun Li round out the main cast as recurring characters. The casting is deliberate, with each actor bringing a distinct energy to the ensemble.
Uwais carries the series. His performance grounds the supernatural elements in something close to reality, and his physicality sells the martial arts sequences without ever needing to explain them. Mann’s Uncle Six provides the emotional anchor, a father figure whose presence gives Kai’s journey weight. Winnick’s Christine Gavin is the practical counterpart, the one who questions the mystical elements while Kai accepts them without hesitation.
The Action
The fight choreography is the centerpiece of “Wu Assassins,” and it is easily the best in the series. The show uses a mix of wire work and practical stunts, with the actors performing their own movements. The result is a kinetic energy that feels immediate and real, even within a fantastical setting.
The amulet Kai absorbs grants him the skill and power of 1,000 monks, and the show spends significant time showing what that means in practice. Each fight is a showcase for the characters’ abilities, and the series rarely repeats itself. From close-quarters grappling to acrobatic strikes, the action is consistently engaging.
The Plot
The plot is where “Wu Assassins” falters. The mystery of the Wu Xing and the five criminals threatening the world is compelling in theory, but the execution drags in practice. The show spends too much time explaining the background of the ancient powers and the history of the Triad, and less time advancing the central conflict. By the final episodes, the stakes feel diluted, and the resolution feels rushed.
There is also a disconnect between the character drama and the action set pieces. Kai’s personal journey — his relationship with Uncle Six, his struggle with the power he carries — is strong, but it often gets sidelined in favor of the larger supernatural threat. The show wants to be both a crime drama and a fantasy epic, and it does not always manage the balance.
The Direction
The direction is confident and polished. The series moves at a brisk pace, and the visual style is consistent across all ten episodes. The cinematography captures the gritty streets of San Francisco’s Chinatown, blending the modern setting with the mystical elements seamlessly. The color grading is warm and saturated, giving the show a distinctive look that sets it apart from other Netflix originals.
The pacing is uneven. Some episodes are slow, particularly those focused on exposition, while others are fast and thrilling. The show could have benefited from trimming the middle section and tightening the runtime, but the final stretch delivers a satisfying payoff.
The Reception
The first season received positive reviews, with critics praising the fight choreography. There was criticism of the plot, though the reception overall was favorable. The show’s popularity led to a standalone film, “Fistful of Vengeance,” which was announced in February 2021 and released on February 17, 2022.
The film continues the story from the ending of the first season. It was released on February 17, 2022, and expands on the mythology established in the series. For fans of the show, it is a natural extension of Kai’s journey.
The Verdict
“Wu Assassins” is a flawed but entertaining series. The action is top-tier, the cast is strong, and the world-building is ambitious. The plot drags in places and the pacing is uneven, but the final stretch delivers. It is a show that rewards patience and offers some of the best fight sequences ever put on screen.
