Films that are made with the intent to
frighten.
Classics of the horror movie genre were filmed thru the 1950's to the mid 1980's. The teen genre, though no stranger to horror movies, is believed to have caused the demise of "true" horror movies in the 1990's.
Typical teen movies now often mix with the horror genre, causing genuine horror movies to often be thought of as
a thing of the past.
