Life-size dolls are replacements for human lovers, babies, and female friends in this empathetic documentary about “doll people” and the alternate realities they create. Director Melody Gilbert casts a wide net, primarily following men who maintain sexual and romantic relationships with life-size RealDolls but also visiting women who have been touched by the phenomenon, like an artist who makes realistic baby dolls for seniors with Alzheimer’s to hold as part of their “cuddle therapy” and another artist who poses sex dolls in purportedly feminist tableaux. The film’s highly effective centerpiece is the story of an odd couple in Chicago, a man and his synthetic “wife” of nearly a decade. When he takes her on dates to the Brookfield Zoo or to his favorite restaurants, what is fascinating is not so much his behavior but how others react to the atypical pair—often mildly, sometimes positively. Gilbert raises the right questions about sexism, modern loneliness, and the slow erosion of the uncanny valley, but without demonizing or even judging her subjects. Instead, she shows how sweet and surprising it can be when humans, faced with difference, choose to be kind.
