★★★★ The only problem with this movie is that it’s ten minutes longer than it needs to be. With few but effective resources, the filmmaker Parker Finn tells the story of a supernatural presence that may actually be part of the unconscious of a psychiatrist harassed by people who smile and die, or smile and kill. It is true that it has somewhat artificial “scares”, but in favor it is necessary to point out that they are usually very original, perfectly diagrammed within the possibilities of cinema. But the most interesting thing, what really transforms the story into a horror movie, is that every moment is unstable. That many of the most terrifying sequences take place in broad daylight (a certain birthday party, for example, is among the outstanding sequences this year). He achieves what any example of this genre should achieve: the absolute instability of our senses, that which causes us at the same time the fear of seeing and the fascination of doing it.
