There are a lot of movies about demons being accidentally unleashed upon our world, but only 1987’s The Gate also features the following: young teen protagonists (one is played by Stephen Dorff, in his feature debut), nightmarish premonitions, a backyard pit that coughs up a cursed geode, evil incantations, heavy metal lyrics, Biblical verses, ghostly construction workers, human sacrifices, and adventures in babysitting.
