As a fan of thrillers, summarize the experience of watching movies, and roughly classify horror thriller movies into six categories. One, psychological thrillers. This style of film is my favorite, because this kind of film has many pits at the beginning, the suspense is sufficient, and the end can not only fill the pits, but also intriguing, and can popularize psychological knowledge. Typical examples are "Split", "Heterogeneous Space", and "Fatal Id". Because most of these films do not have real supernatural events, all phenomena can be scientifically explained, so the horror index is four stars. Two, sci-fi thrillers. Most of these thrillers are related to aliens and monsters. The two are essentially indistinguishable, and both win by eye-popping images and cruel behavior. Typical examples are "Prometheus", "The Monster of the Han River", "The Mist", "Horror Cruise", "Busan Trip" and so on. Some small-cost alien thriller movies are actually very literary, such as "The Night the Stars Are Vast", "The Night the Comet Came", this kind of imagination of the unknown based on scientific basis, let people repeatedly reminisce, the more chewy the more fragrant. Three stars in the Horror Index. Third, the bloody violence category. This kind of movie is completely filled with death and blood plasma, and bluntly tells you what pain is. It reminds me of a crosstalk passage, "You don't laugh, I creak you." "The horror index is as high as four stars, but after reading it, it is over, and I can't taste it when I think about it. Typical of such films are "Chainsaw Horror", "Scream", "Death is Coming" and so on. Fourth, religious witchcraft. This type is based on various legendary witchcraft, and once used to become a tool for harming people, goodness and sin are revealed in the face of superpowers, and the time has come to test the human heart. Such films can be seen in "Master Key", "Nursing Home", "Witch Season". Three stars in the Horror Index. Fifth, fierce ghosts and spirits. This kind of is a classic in thrillers, evil ghosts are impermanent, killing people in the invisible, resentment is long-lasting, the choice of objects is unreasonable, completely random, and the victim can only consider himself unlucky. There are too many such films, "Midnight Bell", "Strange Silk", "Apartment", "Kunyan Pond", "Cry", "Conjuring" series, "Pen Fairy" series. After death, the belonging of the soul and the sustenance of feelings are the eternal unknown, the greatest fear in the human heart.
