18. 'Dark Shadows' (1966-1971)
Supernatural soaps of all stripes can all trace their roots back to Barnabas Collins, the vampire (played by Jonathan Frid) who made Dark Shadows a bright spot on the daytime dial. He didn't even show up on the series until 1967, a year into the atmospheric ABC soap's five-year run, but after being unchained from a coffin, his arrival transfixed the show's young-skewing viewers. From then on, the afternoon serial went from a mildly Gothic story to a full-fledged paranormal romance, mixing witchcraft and werewolves into its sudsy storylines about lost love. It's now the definition of a cult classic.
