This movie has few characters, just the woman and the man helping her. There are a few instances when the audience meets the woman's sister, and the caretaker or manager of the house she rents, but then we are left with the woman and the man she has hired to perform the rituals for her. At first she tells him that she is doing it for love, then she tells him she is doing it to talk to her son, then she tells him she is doing it for revenge, and in the end we find out the truth of what she is doing it for. The man she has hired to perform the ritual is strong in his beliefs and accuses her often of lying to him, which can affect the ritual and cause bad things to happen. In the end the audience finally learns the truth of what has happened, and the truth of what she has been searching for, which is not what was expected.
I'll be honest, I am a little tired of women in these types of movies being whiny and annoying when they don't get what they want. She constantly yells at him, asking him when things are going to happen, and getting angry when she isn't getting the things she wants when she wants them. As a character I didn't care for her and hoped that in the end a demon would eat her. I also didn't care for the occultist she hired because he didn't seem like he wanted to be there. After several mistakes, all made by her, things go in a direction they didn't expect.
I have to say I was not happy with the ending of the movie, and didn't find it satisfying in any way. Even with the twist in the end, I didn't think it was good enough to go with the rest of the movie. There was a build up of suspense, but there weren't a lot of scares throughout. Towards the ending it became a little more frightening, and sad, but the most frightening thing in this movie were the moments when the woman and her son talked to each other through a closed door. It was scary and chilling.
I don't know if I would recommend this movie, but since it is available on streaming, and it isn't a very long movie, take a chance on it and see what you think about it.
