A Haunted House with Mommy Issues
If Indonesian horror films are known for their mix of supernatural chills and tear-jerking melodrama, Kakak takes that formula, polishes it with sincerity, and sprinkles it liberally with ghostly jealousy. Directed and co-written by Ivander Tedjasukmana, Kakak (Sister) isn’t your usual parade of cheap jump scares. It’s an emotional domestic horror movie where the most terrifying thing isn’t the vengeful spirit—it’s your in-laws.
Based on a “true story” (which is always horror code for “we swear this happened to someone’s cousin’s neighbor”), the film blends psychological dread with family drama, resulting in something surprisingly moving. It’s as if The Conjuringgot lost on its way to a séance and stumbled into Terms of Endearment.
Plot: When Having a Ghost Friend Goes Horribly Right
Adi (Surya Saputra) and Kirana (Laudya Cynthia Bella) are the picture of polite, upper-middle-class misery. Married for years, they still don’t have a child. Kirana suffers from asthma, three miscarriages, and a mother-in-law who thinks infertility is a personal failing rather than, you know, biology. Adi’s mother Aida (Ivanka Suwandi) radiates the kind of energy that could sour milk just by glaring at it.
To lift his wife’s spirits, Adi decides they should move to a quiet house outside of town. Because moving to a remote, possibly haunted home has never gone wrong in horror history.
Soon, Kirana starts sensing a presence. But unlike your standard shrieking ghost with eyeliner issues, this one seems… nice. She calls her “SISTER,” because apparently naming the ghost haunting your home is a thing now. Sister comforts her, keeps her company, and provides the emotional support her husband and mother-in-law never could. It’s almost sweet—until Kirana gets pregnant.
Then Sister, like any ex-friend in a Lifetime movie, becomes violently jealous. What follows is part haunting, part custody battle, and part cautionary tale about befriending things that don’t breathe.
Laudya Cynthia Bella: The Saint of Suffering
Laudya Cynthia Bella gives a performance so fragile you want to hand her a blanket and an inhaler. Her Kirana is the emotional core of the movie—a woman whose loneliness is so profound that even a ghost with boundary issues seems like a comfort.
Bella balances fear and tenderness beautifully. You believe she’s both terrified and comforted by Sister’s presence. Her emotional exhaustion feels real; she’s not just scared of a ghost, she’s scared of losing her sanity, her husband, and her identity as a “good wife.”
By the time the haunting escalates, Bella’s haunted eyes do half the acting. It’s a horror movie that makes you feel for the protagonist instead of just waiting for her to scream—and that’s a rare gift.
Surya Saputra: The Husband Who Means Well (and Fails Anyway)
Surya Saputra’s Adi deserves some sympathy. He’s a decent man trapped in a horror movie built entirely out of estrogen and emotion. His solution to everything—“Let’s move!” “Let’s calm down!” “Let’s ignore the ghost!”—proves hilariously ineffective.
Still, Saputra brings warmth and realism to a role that could have been one-note. He’s the kind of man who truly believes home renovation can fix marital trauma. Unfortunately, his new home comes with more than mold and leaky pipes—it comes with a supernatural third wheel.
His descent from patient husband to desperate protector feels genuine. The scene where he tries to fight off a ghost for his wife and unborn child? Equal parts absurd and oddly heroic—like if Bob Vila hosted Paranormal Activity.
The Real Villain: The Mother-in-Law from the Netherworld
Ivanka Suwandi as Aida deserves her own horror spin-off. Before the ghost even shows up, Aida’s constant criticism is already draining the life out of everyone. She disapproves of Kirana, blames her for not producing grandchildren, and seems perpetually one sarcastic sigh away from being possessed herself.
When Sister finally goes full Poltergeist, Aida’s disbelief turns into karmic comeuppance. Watching her get terrorized is both cathartic and darkly funny—it’s like the movie saying, “See what happens when you meddle, Bu?”
Sister: The Friend You Should’ve Ghosted Sooner
The titular “Sister” is no average spook. She’s not here to avenge her death or guard some ancient treasure. She’s just lonely—and violently possessive. Think Casper meets Glenn Close in Fatal Attraction.
At first, she’s practically wholesome, offering Kirana comfort and laughter. But once the pregnancy hits, Sister’s affection curdles into envy. Her hauntings turn cruel, her once-playful whispers become guttural growls, and her invisible hugs become chokeholds.
And yet, there’s an emotional undercurrent to her malice. She’s not evil—she’s just heartbroken, a ghost who’s watching her only friend move on. It’s like watching someone lose a toxic best friend, but with more levitation and spontaneous fire.
Direction: Where Horror Meets Humanity
Director Ivander Tedjasukmana treats Kakak less like a monster movie and more like a sad family portrait that occasionally screams at you. The scares are measured, atmospheric, and steeped in empathy. The haunting isn’t just about creaking floors—it’s about grief, guilt, and the unbearable loneliness of motherhood deferred.
The camera lingers on domestic details—an empty crib, a photograph of smiling faces, a door slightly ajar. When the supernatural finally hits, it feels earned. Tedjasukmana builds his horror on emotional realism: it’s not the ghosts that scare us, it’s what they represent.
The pacing is deliberate, even tender. You don’t get the relentless jump-scare rhythm of American horror. Instead, you get a creeping dread that builds slowly, like a fever.
A Horror Movie with Feelings (and Excellent Curtains)
One of the film’s biggest strengths is its production design. The new home is equal parts dream and nightmare—a spacious, airy mansion where every shadow seems to whisper. The lighting plays tricks on your eyes, bathing everything in muted blues and golds, making even domestic scenes look otherworldly.
The sound design deserves special mention. Sister doesn’t announce herself with orchestra stabs—she sighs, hums, and occasionally giggles in ways that make your skin crawl. It’s unnerving but subtle, like she’s just over your shoulder, reading this review.
A “True Story” That’s Emotionally True
Tedjasukmana has claimed the film was inspired by a real story about a grandfather and his granddaughter, but he’s wisely adapted it into something broader—a meditation on loss, motherhood, and how the living and the dead can’t always let go.
Sure, the “true story” claim is dubious (most “true” ghost stories are about as reliable as politicians’ campaign promises), but the emotions ring true. Everyone’s haunted by something—regret, grief, or in this case, an actual ghost child.
Dark Humor: Because Even Ghosts Need Validation
There’s a twisted humor in watching a ghost act like a jealous sibling. Sister’s spectral tantrums—throwing objects, whispering threats, sabotaging the nursery—are basically what every older sibling has wanted to do when a baby steals the spotlight.
When Kirana sweetly says, “Don’t be jealous, Sister,” it’s so earnest you almost expect the ghost to sit down for therapy. Instead, she hurls a vase. You can’t help but laugh, even as your knuckles tighten around the armrest.
The Ending: Maternal Instinct vs. Ghostly Possessiveness
By the finale, all hell breaks loose—literally and emotionally. Adi must choose between protecting his wife and battling an invisible force that won’t be reasoned with. The climax is fiery, tragic, and strangely moving.
When Sister’s ghost finally confronts Kirana in the nursery, it’s not just a showdown between good and evil—it’s between two women desperate for love. You almost want to hug them both (from a safe distance, of course).
Final Verdict: Heartfelt Horror That’ll Haunt You Softly
Kakak proves that a horror film doesn’t need gallons of blood or jump scares to get under your skin. Sometimes, all it takes is loneliness, longing, and a ghost who just wants to be part of the family.
It’s spooky, heartfelt, and occasionally hilarious in its melodrama. More than a ghost story, it’s a tragic love triangle between a woman, her husband, and her spectral sister.
Rating: ★★★★☆ (4/5)
Family is forever. Especially if one of them doesn’t know she’s dead.
