When I saw the name of the film, I thought it was an ordinary horror movies that could not exceed 5-6 IMDB points, but when saw the IMDB score was 7.5, I thought it was not so. The subject of the film is different and original than the other horror films. The more you watch the more you are deep into it. As a matter of the subject, there is not much dialogue; but the entire film takes place almost in the same area, which makes the it somewhat uninspired.
After a while, the film turns from a horror into an emotional family film. I deduced from the last scene that there would be a sequel.
