It can be said that the director didn't mystify, nor did he reverse or be surprised, but told the audience directly that the family was possessed by evil spirits and was being eaten away step by step. This is the genius of the director. Compared with the related horror films in mainland China, blindly creating gimmicks and foreshadowing for the sake of horror and horror is nothing more than trying to scare the audience, but it is counterproductive. In the film, the director shot in a very real way, and the darkness and closed space (old house and basement) combined with strange sound effects made the original sense of terror more real. At the beginning of the film, the real report about paranormal in the 197s in the United States, which was constructed with a lot of newspaper information, highlighted the rich retro atmosphere of the film. "Evocation" is not particularly scary, but the atmosphere of the film is extremely tense, and the stories are in-depth and interlocking, which makes the audience feel a cold sweat for the family and exorcists in the film.

At last, the film can be described as the climax of the whole film. When the whole family was gradually harassed by evil spirits and could not get away, the exorcist saved the whole family from danger with a thrilling exorcism ceremony. Among them, the mother was possessed by evil spirits and her life was in danger, but with her understanding and understanding of maternal love, they defeated the devil. Motherly love triumphs over evil, which is also in contrast to the legendary witch who killed her son and sacrificed. The title of the film is "Evocation", and the English name of the film "The Conjuring" really means "trick" and "magic", which is not quite the same as the ritual of "Evocation" in China and Southeast Asia. In fact, the film is mainly related to "exorcism", and the whole film is mainly carried out in one room. It is better to use the name "Li Yin Fang" and "Li Yin Fang" in Taiwan Province. However, after watching the film, we can find that while telling this real horror story, the film still does not forget to convey a positive and positive belief, that is, maternal love is paramount.
