Fairy tales aren't always just sweet bedtime stories — sometimes, they take on darker forms that stem from quite a frightening history. Myth, legends, and folklore are powerful vessels of human desires and fears alike, molding tales that blur the lines of magical fairy tales and unsettling truths. Modern TV has done right by the fantasy genre in its exploration of stories that actually work hard for their “happily ever after” through literal blood, sweat, and tears.
