You know. The story, the gestures. You imagine the end. And this mix of familiar, tension and curiosity is the basic motif for see it. Because it is an impecable work, impressive for the fine craft. And for the feeling to be more than a 3 minutes short film but a classic horror, creepy and beautiful and source of real chill. A man front to his door. And the other. Great cinematography, excelent use of details.
