Sadako DX is the movie equivalent of a cursed chain email your aunt keeps forwarding you in 2022: outdated, weirdly desperate for attention, and somehow less scary than your actual inbox. It takes one of the most iconic figures in J-horror history—a vengeful ghost who once made people afraid of television itself—and turns her into the star of a mediocre math problem about viral load and VHS tapes.
On paper, this should have been fun: a supernatural comedy horror riff on Ring, updated for the digital age, with a 24-hour curse instead of seven days and a protagonist who’s a supposed super-genius. In practice, it plays like a parody that doesn’t realize it’s the joke.
The Smartest Girl in the Room… Allegedly
Our heroine, Ayaka Ichijo, is introduced as a prodigy with an IQ of 200. That’s genius, supervillain, and “should probably be solving climate change” territory. In most scenes, however, she behaves like someone whose internet has been unplugged since 1999.
This is the core problem: the movie keeps telling us she’s brilliant, while the script keeps forcing her to do astonishingly stupid things to keep the plot moving. The whole “I’m not scared of the curse, I’ll bring the tape home and leave it lying around my easily tempted family member” move is less “hyper-intelligent skeptic” and more “first-act horror movie cannon fodder.”
Ayaka’s supposed intellect mainly manifests as fast-talking explanations and pseudo-scientific analogies about viruses, none of which are as clever as the movie thinks they are. We’re told she’s a genius; we’re shown someone playing catch-up with a haunted videocassette.
Sadako, Now With 50% Less Dread
Remember when Sadako climbing out of a TV was one of the single most terrifying moments in horror? Here, she’s less a cosmic curse and more a brand mascot desperately trying to stay relevant in the content economy. The tape now kills in 24 hours instead of seven because… the curse “mutated for the digital age.” Faster turnaround time, more engagement, improved user retention—she’s basically a ghostly startup pivot.
Instead of dread, we get gimmicks. The cursed video itself tries to be clever: Sadako climbs out in first-person and shows the viewer their own location in the final shot. It’s a neat visual idea, but the movie treats it like a party trick rather than a source of terror. The follow-up hallucinations—Sadako appearing as people the victim knows—also sound great in theory, but the execution never rises above “mildly spooky filter.”
The tone waffles between wanting to be a real horror sequel and wanting to be a silly meta-comedy, and it ends up being neither particularly scary nor especially funny. Sadako deserves better than being reduced to a cosmic pop-up ad.
Epidemiology by People Who Failed Science
The movie’s big “innovation” is treating the curse like a virus and leaning hard into infection metaphors. At first, there’s a new, faster, deadlier strain from the darknet. Then Ayaka teams up with a hikikomori germaphobe called Kanden, who treats the tape like a supernatural smallpox sample. So far, so interesting—if you’re going to retool Sadako for modern times, making her a viral meme of death isn’t the worst idea.
But then comes the “theory.” First, they decide group viewership “spreads the curse thinner,” like a vaccine, so each viewer gets a non-lethal dose. Later, they pivot to repeat viewership: if you keep rewatching the tape at least once every 24 hours, you somehow “maintain immunity.” The logic is so tortured even Sadako would walk away.
We’re never given a reason this should work beyond “because the plot says so,” and the movie seems smugly proud of this half-baked metaphor. It wants to be clever commentary on pandemics, mass media, and viral spread. It mostly feels like watching people misuse medical terminology to justify binge-watching their own doom.
Master Kenshin, Discount Showman of Evil
Then there’s Master Kenshin, the psychic/fortune teller who introduces the tape on a variety show, gets Ayaka involved, and turns out to be responsible for spreading the curse in the first place. His motivation? Not revenge, not ideology—ratings.
Yes, Sadako DX makes its primary human antagonist a guy who weaponizes an ancient death curse to drive engagement for his TV career. Which could’ve been a biting satire of media exploitation… if the movie bothered to actually explore that angle instead of just dumping it in a late reveal.
His backstory—growing up at a shrine, watching his father perform fake exorcisms, becoming disillusioned, then deciding his “destiny” is to feed people’s desire for excitement—is thrown at us mostly in monologue. It doesn’t land as tragic or complex; it lands as, “Oh, he’s just a clout-chasing idiot with access to supernatural content.”
He promptly dies of the curse right after explaining himself, mostly to prove Ayaka’s “group viewership is a vaccine” theory wrong. The moment should be shocking or darkly funny. It mostly feels like the movie killing off an interesting villain concept before it does anything interesting with him.
Horror, But Make It Scheduling
By the time the movie reaches its climax, the stakes have devolved into something truly absurd: everyone has to keep rewatching the cursed tape every 24 hours, or they die. Not break the curse, not destroy Sadako, not end the cycle—just build your entire life around appointment viewing like it’s a ghost-powered streaming subscription.
So Ayaka, Oji, Kanden, Futaba, and Mom are all stuck in a grim version of a watch party, rewinding their VHS like their lives depend on it—because they literally do. This could’ve been played as bleak cosmic horror: humans trapped in an endless ritual to placate an indifferent force. Instead, it’s treated almost whimsically, as if someone just realized, “Wouldn’t it be funny if the curse was basically a daily chore?”
The epilogue, where they gather on video chat to rewatch again before their deadlines, turns the whole curse into a punchline about forgetting to rewind the tape and your phone battery dying at the worst possible time. It’s not scary, it’s not particularly sharp, and the tension is about as intense as misplacing your TV remote.
Sadako, Now in XXL
And then there’s the post-credits scene: a gigantic Sadako climbs out of the well into a movie theater, towering over the audience before turning to reveal the word “END” on the screen.
You can see what they were going for: a final meta gag about Sadako breaking out of the tape and franchise cycles, looming over the audience, cinema itself being haunted, etc. In reality, it looks like the movie gave up on story and went, “Fine, big Sadako go boom.”
If you grew up terrified of that long-haired figure crawling out of static, seeing her Godzilla-sized in a theater full of screaming extras doesn’t deepen the myth; it cheapens it. She stops being uncanny and becomes a meme.
Wasted Potential, Wasted Ghost
The cast isn’t bad. Fuka Koshiba does what she can with Ayaka, Kazuma Kawamura’s Oji has some decent comedic beats, and Mario Kuroba’s Kanden is at least memorable as the anxious shut-in scientist. But they’re all stuck in a script that doesn’t know whether it’s more interested in mocking itself or being taken seriously.
Sadako DX wants to have it all: meta-commentary, pandemic allegory, slapstick comedy, and genuine scares. But it never commits to any of those modes, so everything lands at half-strength. The jokes rarely go all the way into absurdity, the horror never fully digs under the skin, and the commentary is too shallow to resonate.
What’s most frustrating is that buried somewhere in this mess is a solid idea: updating the curse for the digital age, critiquing viral culture, exploring how people exploit fear for attention. Instead of exploring that, the movie skims the surface and settles for goofy theorizing about cursed herd immunity.
Final Verdict: Buffering… Forever
Sadako DX isn’t the worst thing to happen to the Ring franchise, but it may be the most pointless. It turns an iconic horror myth into a convoluted science project and then forgets to be either truly funny or actually frightening. What was once a primal terror about technology and repression is now a movie about very stressed people trying to keep up with a viewing schedule.
If you’re a die-hard completist, you might watch this out of obligation, the way the characters keep rewinding that tape. Everyone else can probably skip it without fear of vengeful spirits—just the mild curse of having missed 100 minutes of unintentional self-parody. Sadako deserves a better resurrection than this.
