There must be at least a hundred great horror films.  Determining the top hundred is easy, the top five impossible. Rather than omit too many of the greats, and tempt film buffs and the undead into vengeful revolt, here’s instead five of the best.  All prised from a seething mass of horror, and chosen because they tell the story of something very specific: that moment when dread arises out of the banal, and lingers, sticking to the skin like cold damp ectoplasm, for days and weeks.  An overwhelming melancholy dread, inspired by loneliness, at times feared more than death.
