One or two children have been sent elsewhere, because the presence of babies is too restrictive to create an atmosphere of terror
2. The little boy was already possessed when he returned

Finally, I would like to express my opinion. The main purpose of horror films is to scare people. If the plot is mediocre, I think it is understandable. On the contrary, I don't think a movie like "Master Key" is a horror movie, it can only be said to be a drama or a suspense movie, because it is not scary at all.
