October, the month of horror, has come to an end. While choosing the best horror film can be challenging due to varying tastes, a recent scientific study has delivered its verdict. Researchers have determined the movie that scares its audience the most based on its impact on heart rates.

What is the scariest horror movie?

The Science of Scare Project conducted an experiment, monitoring the heart rates of 250 people to create a scoring system called the Scare Score. The results showed that Sinister (2012), directed by Scott Derrickson, takes the title of the scariest movie of all time.

The film’s synopsis reads: “A journalist travels with his family while investigating brutal murders to write about them. Upon arriving at a house marked by tragedy, he discovers snuff films containing horrific clues, setting off a chain of events beyond his comprehension.” Sinister is available on your favorite streaming platform for those who want to experience this level of fear.

The cast is led by Ethan Hawke as Ellison Oswalt, alongside Juliet Rylance as Tracy Oswalt, Clare Foley as Ashley Oswalt, Michael Hall D’Addario as Trevor Oswalt, and other talented actors who contribute to the film’s unsettling atmosphere.

With a 63% score on Rotten Tomatoes and 155 reviews, the movie has received mixed opinions. While some consider it reliant on clichés, many agree that Sinister offers fresh, disturbing twists that manage to surprise and scare even the most seasoned horror fans.
