Nightborns intense ending, explained

Hanna Bergholm's Nightborn presents a terrifying and disturbing tale of parenthood, delving into the messy and often "ugly" aspects of parental love. The film stars Seidi Haarla as Saga and Rupert Grint as Jon, who are newlyweds who have moved from London to start a family in Saga's childhood home in the Finnish woods. The house they move into is a fixer-upper, with rotting floorboards, peeling wallpaper, and actual trees growing through its structure.

The couple quickly conceives their child, Kuura, but things take a bizarre turn when Kuura is born. Kuura is gremlin-like, burns in sunlight, hates clothes, and thirsts for blood. The film delves into the strange and often violent relationship between Saga and Kuura as they grapple with each other's differences and the increasingly creepy nature of the child.

The film culminates in a wild and chaotic ending, where Saga and Jon violently wrestle with each other over Kuura, and Kuura ultimately feeds on Jon before sharing his heart with Saga. The film ends with Saga sending Kuura off into the woods with a weary smile, and the trees around them coming to life, confirming they are magical beings.

The film's ending can be interpreted as a connection to Nordic folklore, specifically the mythological beings known as trolls. These creatures are confirmed in the film's credits and are said to be connected to Saga's family for generations. The film explores the idea that some humans carry a "bit of troll's blood," making them feel different, awkward, or out of step with social norms.
