It's not a horror movie, it can only be said to be a psychological fable. The hostess husband died while sending the hostess to the hospital to have a child. The son's birthday is the husband's death day. The heroine pulls the child to grow up alone, bears all the troubles and pressures of life alone, does not have the opportunity to examine her own heart, nor realizes that she is still immersed in the pain of losing her husband and cannot extricate herself, let alone knowing that she is in her own heart. The pain has been angered to his son. But all of this is traceable. For example, she rejected her son’s overly intimacy to her, and her son was not allowed to talk about her husband’s death. Another example: when she was about to collapse, she said to her son: I would rather die. You, not him... Babadu is not so much a monster, but a demon caused by the heroine's long-term depression and nowhere to relieve the trauma. Fortunately, the love of the children finally awakened the mother's reason and defeated the demons. Regarding the ending: Babadu was not defeated, but locked up, which also shows that the inner demon is not so easy to defeat. I think the director handles this very well, dealing with psychological problems, instead of blindly denying it and suppressing it, but trying to accept its existence, and then try to get along with it, until finally he grows strong enough to not be influenced by it. There is a sentence in the ghost book in the play: The more you deny me, the stronger I am. Deeply agree
