"Persona" has been called an experimental film. Singer acknowledged Marc Gervais's theory that its style is a postmodern rejection of "realistic narration", although he said this was of secondary importance to its commentary on cinema. "The Independent" journalist Christopher Hooton said that symmetry was used and the fourth wall sometimes broken, quoting essayist Steven Benedict on the use of "reflections, splitting the screen, and shadows". The fourth wall seems to break when Alma and Elisabet look into the camera and when Elisabet takes photographs in the direction of the camera.
