"Any great horror movie will leave both fans and film critics unsettled and with a fresh and lasting impression.
Critics frequently gravitate toward horror films that produce what they deem to be noteworthy innovations on the well-established tropes of the genre.
The Rotten Tomatoes' list we compiled here from the site's most critically heralded horror movies includes all acclaimed films that feature a "horror" tag. This resulted in a list that spans traditional horror films, horror-comedies, and outright horror parodies.
The list ranks the movies by an adjusted critical score that Rotten Tomatoes derived from a weighted formula to account for the variation in number of reviews for each film."
