All I can say is that I'm very disappointed with the ending! (Spoiler alert)

Originally, the foreshadowing was quite good, the nervous policeman, the sleepwalking little boy, the little girl who loved to draw, the old professor who studied symbols, and even the secretary who appeared behind the old professor. It's a story that doesn't disappoint, but as a result, there are all kinds of people passing by, all kinds of positive characters, and there is only one bad guy, the "cuckoo", one can be captured by a video recorder and can be reflected by a mirror, but. Is my heart too dark? Hope the more bad guys the better? I'm still wondering if I can manipulate the secretary to kill the old professor in front of the video. Ha ha! The most classic movie like this should be "The Shining", right? There are also many characters in it, but they are all concentrated. When I say concentration, they all have the same purpose, which is to make the male protagonist crazy.
Actually I've been looking forward to being a pervert killer, step back or even someone with the ability to manipulate human minds doing these things. For example, the young policeman later found out that the policeman was really a loyal assistant, but he appeared so neurotic at first, but later became so wise, did he want the audience to think that he was hiding? The old policeman is just playing soy sauce, he should be able to make a big fuss about him, right? The old professor was born for the symbols in the movie. I think it would be more interesting for the protagonist to look up the book by himself. It may be better to give the old professor's role to the sleepwalking boy and the little girl who loves to draw.
In the end, it was a demon who manipulated the child to kill people. He killed so many people just to get the child, so he just kidnapped him. Do you want to highlight the demon's bloodthirsty?
Or this is the film's intention to make an unexpected ending. It is indeed unexpected, but there are too many surprises, but this is the way the film is. Just watch it, and the filming is done, even if the audience thinks of more. A better ending and a better plot don't help either.
In fact, I didn't quite understand this movie review myself. Maybe I haven't written anything for a long time, and my ability to organize language is much worse. I can't express what I think in my heart. I hope someone can understand me. what is it?
