Smile

Parker Finn's Smile took a simple, primal concept — what if a smile meant you were going to die — and turned it into a $217 million box office phenomenon. Sosie Bacon delivers a committed, physically grueling performance as Dr. Rose Cotter, a therapist who witnesses a patient's violent death and finds herself stalked by an entity that wears the faces of people around her, always smiling. The film's marketing campaign — planting grinning actors at live sporting events — was genius, but the film itself earns its scares through Finn's understanding that a human smile, held too long and too wide, triggers a deep uncanny valley response. The birthday party scene is one of the most uncomfortable set pieces of the year. Finn elevated what could have been a gimmick into a genuine exploration of trauma, mental health stigma, and the cycle of suffering.
