After Yang is probably the coziest science fiction movie this year. Directed by Kogonada, the film takes place at some point in the indeterminate future following an unspecified calamity and follows a young family who struggles through the loss of their android (the titular Yang, played by Justin H. Min), who serves as both a caregiver and a sibling for an adopted daughter.
The movie touches on all kinds of subjects, from transracial adoption to what it means to be human, but much of its worldbuilding comes from, well, the world. Few specific details are given about the time or place in which the movie is set or the events that led to the almost postapocalyptic world the characters dwell in. That means that the visual design did a lot of heavy lifting in terms of storytelling.
