Some horror movies became classics thanks to their influence, legacy, and impact on the genre, and among them is John Carpenters Halloween, but some harsh realities come up when rewatching it decades later. In 1978, John Carpenter brought the slasher film Halloween, which introduced a new masked slasher villain called Michael Myers. Although it wasnt well-received by critics during its initial release, Halloween is now one of the most influential horror movies ever made, as it was key in developing the slasher genre in the 1980s.
