The Shining (1980)

Face it, every Halloween party debates whether 'The Shining' is the creepiest classic ever—or just a two-hour scenic tour of Jack Nicholson's unraveling sanity. Between 'Redrum' and those eerie twins, the movie's a lock for sparking fan obsessions and heated GoatWars throwdowns. Ever tried arguing its merits with someone who doesn't get the allure of a haunted hotel? Yeah, good luck convincing them why your sleepless nights are worth it!
