Sheep in the Box Movie Review: A Beautiful AI Fairytale (2026)

The Haunting Beauty of 'Sheep in the Box': When Grief Meets Technology

There’s something profoundly unsettling yet utterly captivating about Hirokazu Koreeda’s latest film, Sheep in the Box. On the surface, it’s a story about a family grappling with loss in a near-future world where technology offers a bizarre solution to grief. But personally, I think Koreeda has crafted something far deeper—a meditation on what it means to mourn, to remember, and to find solace in the most unexpected places. What makes this particularly fascinating is how he transforms what could easily be a dystopian nightmare into a tender, almost fairytale-like exploration of humanity.

The Allure of REBirth: A Modern-Day Faustian Bargain?

At the heart of the film is REBirth, a company that offers grieving families a chance to ‘rent’ humanoid robots modeled after their deceased loved ones. On paper, it sounds like the stuff of sci-fi horror—a corporation profiting from pain. But what many people don’t realize is that Koreeda doesn’t villainize REBirth outright. Instead, he uses it as a mirror to reflect our own complexities about loss. Otone, the grieving mother, is drawn to the idea, while her husband Kensuke is skeptical, calling the company ‘hyenas.’ This tension isn’t just about technology; it’s about how we cope with the void left by those we’ve lost.

From my perspective, the brilliance here lies in Koreeda’s refusal to take sides. He doesn’t judge Otone for her desperation or Kensuke for his resistance. Instead, he invites us to sit with the discomfort of their choices. If you take a step back and think about it, REBirth isn’t just a company—it’s a symbol of our collective struggle to accept mortality. And that’s what makes it so hauntingly relatable.

Kakeru’s Return: A Robot or a Resurrection?

The arrival of Kakeru, the couple’s deceased son, in the form of a humanoid robot is where the film truly shines. Koreeda handles this ‘unboxing’ with such delicacy that it’s impossible not to be moved. Otone’s joy is palpable, but Kensuke’s unease is equally compelling. He dismisses the robot as a ‘Tamagotchi,’ a Roomba, anything but his son. But is he right?

One thing that immediately stands out is how Koreeda avoids the obvious pitfalls of this premise. He doesn’t turn Kakeru into a sinister AI gone wrong or a mere tool for emotional manipulation. Instead, he explores the possibility that this robot could be a bridge—a way for the family to heal. What this really suggests is that grief isn’t linear, and neither is love. By the end, Kensuke’s gradual acceptance of Kakeru feels less like a surrender to technology and more like a quiet acknowledgment of his own humanity.

The Fairytale Element: A Masterstroke of Storytelling

What sets Sheep in the Box apart is its blending of genres. Koreeda weaves elements of Pinocchio, The Little Prince, and even biblical allusions (Kensuke’s profession as a carpenter is no accident) into a narrative that feels both ancient and futuristic. This raises a deeper question: Are we watching a sci-fi drama or a modern fable?

In my opinion, it’s both—and that’s the genius of it. The ethereal soundtrack and stunning visuals only amplify this duality, creating a world that feels dreamlike yet grounded. Koreeda isn’t just telling a story about a family; he’s crafting an allegory about rebirth, both literal and metaphorical. A detail that I find especially interesting is how the film never explicitly answers whether Kakeru’s presence is a blessing or a curse. It leaves that interpretation to us, and that ambiguity is what lingers long after the credits roll.

Haruka Ayase’s Performance: The Soul of the Film

No discussion of Sheep in the Box would be complete without mentioning Haruka Ayase’s extraordinary performance. Her portrayal of Otone is a masterclass in subtlety—a woman torn between hope and despair, between memory and illusion. What makes this particularly fascinating is how Ayase conveys so much with so little. Her wide-eyed wonder when she first sees the humanoid robot in the cafeteria is heartbreaking, as is her quiet devastation when Kensuke rejects Kakeru.

Personally, I think Ayase’s performance is the glue that holds the film together. She embodies the film’s central tension: the desire to hold onto the past while desperately reaching for the future. It will be fascinating to see what she does next, but for now, this role cements her as one of the most compelling actors working today.

The Broader Implications: Technology, Grief, and What It Means to Be Human

Koreeda’s film isn’t just a story about one family; it’s a commentary on our relationship with technology and our fear of mortality. In a world where AI and robotics are advancing at an unprecedented pace, Sheep in the Box forces us to confront uncomfortable questions. Would we use technology to resurrect a loved one? And if we did, would it bring us peace or more pain?

What many people don’t realize is that Koreeda isn’t just asking these questions—he’s challenging us to rethink our answers. The film’s ending, with its quiet sense of hope, suggests that perhaps the line between human and machine isn’t as clear as we think. If you take a step back and think about it, the real rebirth in the film isn’t just Kakeru’s—it’s the Komotos’, and by extension, ours.

Final Thoughts: A Film That Stays With You

Sheep in the Box is the kind of film that lingers in your mind long after you’ve left the theater. It’s beautiful, it’s unsettling, and it’s profoundly human. Koreeda has taken the stuff of dystopian nightmares and turned it into something elegiac, something that feels like a whisper rather than a shout.

In my opinion, this is one of his most ambitious and successful works to date. It’s a reminder that even in the face of loss, there’s always room for hope—and that sometimes, the most unexpected things can help us find our way back to ourselves. What this really suggests is that grief, like love, is a force that can’t be contained—not even by technology. And that, perhaps, is the most beautiful fairytale of all.
