There are haunted house flicks, and then there’s Poltergeist. Featuring some of the most iconic imagery and words—“they’re here!”—in modern horror, it’s a film that continues to scare the hell out of audiences, no matter how many times they’ve seen it. The story of a suburban California’s family home occupied by malevolent spirits that abduct the youngest daughter, has spawned two sequels and endless imitators, none of which can rival this one.
