The plot is compact and natural, although the murderer has never shown his face, but this is where he is clever. The atmosphere and plot are pushed to a climax through the horrible and tense atmosphere and the creation of the mysterious image of the murderer.
At the end, the sound of the radio reappears, which is thought-provoking and exacerbates the horror atmosphere, making the plot unconventional.
Personal rating of 8.0 (there are factors that resist certain pretending literary youth). Horror films are originally based on psychological stimulation and atmosphere plot creation to attract people. Do they have to understand some profound principles of life? In general, it is better than most horror movies such as "Fatal Turn" and "An Eye Behind the Mountain".
Don't talk about it, go see the second one!
