The movie Shirley presents a psychological drama based loosely on the life of Shirley Jackson, intentionally mixing reality and invention that could potentially distort the truth about those who were actually involved. Even with historical errors and reservations voiced by Jackson’s relatives, the film is notable for its powerful acting and deeply felt character studies. The unclear resolution leaves audiences to draw their own conclusions from the narrative, which seems to touch on complex ideas related to artistic expression, self-perception, and psychological instability.
