Metamorphosis (2019) is a Korean supernatural horror film that blends possession, family trauma, and religious fear into a chilling and unsettling story. Directed by Kim Hong-seon, the movie follows a family whose life slowly collapses after a demonic presence enters their home. Instead of relying on cheap jump scares, the film builds tension through psychological horror, disturbing imagery, and the terrifying idea that evil can hide behind the face of someone you love.

The story revolves around Joong-Soo, a priest known for performing exorcisms that sometimes go horribly wrong. When he tries to protect his family from a demonic force seeking revenge, the evil begins to change the behavior, faces, and even personalities of family members. The film’s title perfectly reflects its most horrifying concept: anyone can turn into something monstrous at any time. This creates continuous paranoia, as the audience never knows who is truly possessed.

Performances are strong, especially Bae Sung-woo, who delivers a powerful emotional depth as a guilt-ridden priest, and the actresses playing the daughters bring vulnerability mixed with fierce terror. The cinematography uses dark, confined spaces to intensify the sense of suffocation, while the makeup and sound design elevate the more grotesque moments.
