I am no expert. I have seen a few horror films over the years. I recently plunged back into a few of my favorites. They reclaimed their titles of being "great." I notice they are from a certain time and place. Formative of my own personal mythology.
The best horror is the horror that is closest to us. These films hit the bullseye. What's funny is that all of these films are quite successful as horror films, and at the same time, they are absolutely hilarious. The hilarity comes out of the deep unease of the horror. Finally, you just have to laugh.
These films are about the calamity and catastrophe of being a human being.
Brian De Palma's "Carrie." (1976). Based on a Stephen King novel. The horror of puberty, the horror of high school in America, the horror of teenage boys & girls, the horror of organized religion, the horror of oppressive adults.
Stanely Kubrick's "The Shining." (1980). Based on a Stephen King novel. The horror of being a child, captive to two very limited, and conflicted human beings, also know as the parents. The horror of alcoholism, and the horror of the snaky, creepy ways the human mind can go off the rails. The horror of seeing, & being seen, clearly.
David Cronenberg's "The Fly." (1986). Based on a George Langelaan short story. The horror of the human body. The horror of aging, morphing, evolving. The horror of having no control over how your body changes over time. The horror of becoming.
Really, these three films kind of sum up the complete horrorshow of being a human being.
Let me throw one last film into the mix.
John Huston's "Wise Blood." (1979). Based on a Flannery O'Connor novel. Some call this a "black comedy," but it's also a horror film. The horror of faith & religion, the horror of of Jesus, sin, guilt, & judgement, the horror of the American South, the horror of racism, and human ignorance, the horror of Christianity writ large, the horror of puritanism, the horror of human small-minded-ness, the horror of rural communities, the horror of small-town America, the horror of slavery, sexism, & misogyny.
All these films are creepy, disturbing & fun; super-funny and so fucking great. Great film-making & story-telling. All are reminders of the horror that engulfs us. We live within the contours of a landscape of horror. Good luck dealing with that my friends.
