Pet Sematary, at least at the time Stephen King wrote his 2001 introduction, was the most frightening book he’d written, according to the author. He explains that for any parent the death of a child is perhaps the most traumatic event they might ever face. The only thing worse would be if s/he came back to life, not him- or herself. Two major films were made based on this novel, one in 1989, directed by Mary Lambert and a second in 2019 by Kevin Kölsch and Dennis Widmyer. Resurrection is a frightening idea. It claws out of the ground of religion.
The entire premise of resurrection, to those in the western hemisphere, derives from Christian teaching. Among the many movie monsters, two revenants in particular—the resurrected and the zombie—inspire a special fear. Is it because religion tells us that at least the former is actually possible? Horror derives much of its energy from the fear of death, and the living dead of either stripe have religious origins and cross boundaries that are carefully guarded.
