After watching the film, the old exorcist Elise Rainier found that there are two different opinions about the ending of the film on the Internet. The difference is mainly in the father Josh. One theory is that Josh is helping his son return to the underworld of the flesh. After the trip, the old woman took over his body; another way of saying it is that the old woman had already taken over Josh's body when he was 8 years old. I support the latter view. But after reading a lot of comments, I felt that they were not elaborate and systematic enough, so I simply pulled the film from beginning to end to clear the plot clues of the film. Those who have different opinions or are also seeking arguments can discuss them together.
Lambert and his son are both people with the ability to escape from the body. Once their souls are out of the body for a long time, they will be remembered by ghosts floating in the underworld, and they may be occupied by ghosts. The film is mainly divided into two lines, one open line, tells the story of the fight and anti-scramble between the elder son Dalton and the red-faced ghost, and the other is a hidden line, tells the story of the fight and anti-scramble between father Josh and the old ghost woman. The brilliance of this film is that its main line is not the open line, but the dark line. At the beginning, it is hidden deeply, and as the plot deepens, it surfaced a little bit, and it was not until the end that people suddenly realized it.
