Hirokazu Kore-eda has built a career on families that don't look like the ones on paper, and Sheep in the Box gives him his strangest premise yet without losing his usual patience for domestic detail. A couple unable to have a child receives a seven-year-old humanoid companion, built to be raised as a son in every meaningful sense. The film is far less interested in the science of how he came to exist than in the much harder question underneath it: what, exactly, does it mean to be someone's parent, and does the answer change once biology is out of the equation entirely?
Kore-eda's gift has always been for treating extraordinary premises with completely ordinary attention, and that instinct serves the film well here. Bedtime stories, arguments over screen time, a quiet car ride home — the film builds its case for this family's legitimacy almost entirely through accumulated ordinary moments rather than through any big argumentative speech. The son's difference is acknowledged, occasionally addressed directly, but mostly folded into the texture of a childhood that looks a great deal like anyone else's.
The film is smart enough to let the parents' fear be about themselves as much as about their son — not just what he is, but whether they're equal to what they've chosen to become.

The performances hold the whole thing together. The mother's careful, sometimes overcorrecting tenderness plays as entirely earned rather than performative, and the father's slower, more skeptical arc toward acceptance gives the film its most affecting turn. The child actor at the center of it all resists every temptation to play the role as either uncannily robotic or conventionally adorable, landing instead on something genuinely unplaceable, which is exactly what the film needs from him.
Where it stumbles slightly is in a subplot involving the wider world's reaction to the boy's existence, which raises real questions about how a society would actually treat a child like this and then largely declines to follow through on them. The film is clearly more interested in the family's internal experience than in the social debate around it, which is a defensible choice but leaves a few threads feeling underexplored.
