Worst Horror Movies of All Time

Print Email

Watching a good horror movie can be one of the most intense cinematic experiences a person can have. Horror films can create a visceral experience for the viewer, with levels of fear resulting in increased heartbeat, sweating, and involuntary screams of terror.

Of course, not all horror movies are good. The genre is filled with cheap effects, nonsensical plots, and laughably poor acting – sometimes all in the same film. And while these “bad” horror films will almost always have supporters, they are cinematic torture for the average filmgoer.

24/7 Wall St. looked at user and critic online ratings of horror films to determine the worst of the genre. These are the movies that audiences simply cannot help but voice their utmost displeasure with.

The horror category is known for its shameless production of sequels to popular films. Sometimes these sequels become hits on their own merits, as is the case with “The Texas Chainsaw Massacre 2” and “Evil Dead 2.” Generally, however, these movies pale in comparison with the original. Among the 100 worst horror movies of all time, 18 are sequels.

The list also contains multiple remakes of popular films, including the 2009 remake of “Night of the Demons” and the American remake of South Korean film “Addicted” entitled “Possession.” Also included are films that attempted to ride the coattails of similar movies yet failed to leave the same impression, such as 1984’s “Ghoulies,” a movie about small, chaotic monsters like those found in the Gremlins series.

And while the list contains movies going back to the 1940s, the decade with the most entries is 2000 to 2010, when nearly two out of every five films listed came out. The horror genre undoubtedly had trouble finding its footing during this period – most movies were dark and humorless and often relied on cheap-looking computer-generated special effects.

To determine the worst horror movies of all time, 24/7 Wall St. created an index based on each film’s Rotten Tomatoes average critic rating, Rotten Tomatoes average audience rating, and Internet Movie Database average user rating. To be considered, each film needed to have at least 10,000 total user votes between IMDb and Rotten Tomatoes, as well as 10 approved Tomatometer critic reviews, and be categorized as “horror” on IMDb. We averaged the user ratings from Rotten Tomatoes and IMDb, weighted by the number of votes for each. The combined user rating was then averaged with the Rotten Tomatoes critic rating. Domestic box office gross data comes from reporting service Box Office Mojo and is not adjusted for inflation. Films missing box office data either did not receive a theatrical release, failed to gross a significant amount, or did not have data available from their release dates.

Certain films that were considered as being too far outside the genre were removed from consideration.
