10 Scariest Horror Movies of the Last 20 Years According to Collider

Horror has consistently maintained itself as one of the most prolific and effective genres of filmmaking, with its inherent ability to frighten and keep audiences on the edge of their seats being second to none. There have been a wide array of deeply influential films that have made their mark not just on the filmmaking landscape, but wider pop culture as a whole through frightening audiences worldwide. However, audiences have largely evolved past the now simple scares of earlier decades, forcing modern horror films to constantly evolve and break new ground in terms of fear factor. This has laid the way for many modern horror movies to reach previously untold levels of tension and fear, being some of the scariest movies ever put to film in the constant arms race to cater to desensitized audience demands. One can only assume that many will look back on the horror icons of the past 20 years in the same way that people look back on films like The Exorcist.
