Netflix’s new sci-fi thriller avoids a pitfall even Steven Spielberg fell for

With Hollywood running out of interesting ideas, nostalgic remakes are a dime a dozen. Disney is the biggest culprit, reproducing animated favorites in live-action form almost beat-for-beat with little to no emotional resonance that made those films special in the first place. But even the best directors fall prey to the legacy reboot trap, like Gus Van Sant’s Psycho (1998), Steven Spielberg’s West Side Story (2021), Spike Lee’s Highest 2 Lowest (2025), and Edgar Wright’s Running Man (2025).

The revival of The Human Vapor as a TV series had me worried Netflix would fall down the same path as so many before it in this adaptation of a Toho cult classic. (After all, the streamer has released plenty of breathless adaptations that miss the point entirely in the past.) The story takes inspiration from Ishirō Honda and Takeshi Kimura’s groundbreaking 1960 tokusatsu film — a Japanese sci-fi spectacle like Godzilla (1954) built around practical special effects — but the plot is entirely different, and it’s all the better for it.

The original thriller focused on a tragic science experiment that transforms a down-on-his-luck bank robber into a man capable of turning himself into gas, playing like a crime melodrama with horror undertones. Series writers Yeon Sang-ho (Train to Busan, Hellbound) and Ryu Yong-jae (Parasyte: The Grey), alongside director Shinzo Katayama, reimagine what that central idea might look like if stretched across a serialized mystery, where the horror isn’t just the condition itself, but the web of institutions and personal motives that grow around it. Through this approach, Netflix’s Human Vapor retains that same unique blend of genres as the original film, but uses them in its own interesting ways.

The story kicks off with a bloody bang, both metaphorically and literally. In the middle of a live interview with fiercely determined Japan News Television journalist Kyoko Kono (Yu Aoi), environmental energy expert Professor Sano (Morley Robertson) suddenly explodes into a gory mess of blood and internal organs after a rogue cloud of smoke billows up his pants. While the VFX work isn’t the best — the professor rising in midair looks artificial and the “smoke” can be unconvincing — it still gets the point across: this is an entirely new direction for The Human Vapor, and we’re leaning into it.

The first two episodes follow Kyoko and detective Kenji Okamoto (Shun Oguri) as they work the case from different angles. The pair also have some not-so-subtle romantic history, creating an interesting dynamic as they dive deeper into the mystery on their own terms. While Kenji focuses on the broadcast recording, searching every camera angle for clues of external tampering or gas leaks, a mysterious, empty box that arrived at the newsroom moments before the interview leads Kyoko to a secret recording of the perpetrator himself, who aptly identifies himself as the “Human Vapor.”

Expertly played by Uta Uchida, a Japanese model making his acting debut, the villain of Human Vapor casts an unsettling presence. Uta delivers dialogue in a very soft, slow monotone that makes him all the more eerie. The final few scenes of episode 1 are the most impactful, putting the Human Vapor in a literal interview chair before devolving into an action sequence. The show does an excellent job of making the villain feel omnipresent with clever tricks, using lingering smoke from a car engine, cigarette, or small campfire to keep both the characters and the audience on edge.

Later episodes begin to unravel this complex web of secrets further by introducing a brother-and-sister live-streamer duo in Kaho (Suzu Hirose) and Fujita (Kento Hayashi). Their livestream antics initially feel cringey tonally off with the grounded investigation unfolding elsewhere, but Hirose and Hayashi have a natural chemistry that makes their sibling banter authentic rather than forced, and cleverly turns them into the audience’s stand-in. These aren’t seasoned detectives or journalists armed with institutional resources, but ordinary people drawn into the same spiraling mystery as everyone else. It’s fitting, then, that the show’s most unlikely duo stumbles upon one of the most important pieces of the entire puzzle.

That same confidence extends to Human Vapor’s yakuza storyline, led by the criminal-turned-businessman Yasutoshi Mori (Yutaka Takenouchi) and the Kurose-gumi crime syndicate. Rather than treating organized crime as a convenient obstacle for its heroes to overcome, Sang-ho folds the underworld into the show’s larger conspiracy with surprising restraint. Kurose-gumi becomes one more institution vying for power and information, its motivations colliding with the police, the media, and the mysterious Human Vapor himself in ways that continually reshape the investigation. Every new faction introduced in the series expands the world instead of distracting from it, making the central puzzle feel genuinely sprawling without ever becoming overwhelming.

Few shows can convincingly juggle so many genres — science fiction, noir mystery, crime drama, romance, political conspiracy, and body horror — without collapsing under their own ambition. But Human Vapor triumphs by making those disparate pieces feel like they naturally belong together. The show also embraces its tokusatsu roots with ambitious visual effects — like nail-biting action scenes with the Human Vapor and large-scale destruction in urban settings — set across Japan’s mountains, coastlines, and quiet rural towns. That wider sense of place gives the mystery room to breathe, making the country feel like just another character caught in the Human Vapor’s ever-expanding web.

Human Vapor succeeds where so many legacy reboots stumble by treating Ishiro Honda’s 1960 classic as the foundation for something new. The result is a confident expansion of an already fascinating premise — one that trusts its characters enough to forge their own identity. If this is the blueprint for revisiting Toho’s forgotten classics, like H-Man, Atragon, or Metango, then Human Vapor proves the studio’s rich back catalog has far more to offer than kaiju spectacle.

Human Vapor releases on Netflix July 2.
