With all due respect to Poltergeist (They're her-rrrre!"), you don't need to live in a haunted suburban house to get sucked into the terror of your television. From the short-story-like psychological shocks of Sixties name-brand anthology shows to today's cable-abetted blood-and-guts extravaganzas, many of the medium's most memorable series have centered on things that go bump in the night. With Halloween approaching, we're counting down the top 25 horror shows in TV history. Vampire slayers and sexed-up bloodsuckers, brainiac serial killers and brain-chomping zombies, paranormal activities and portly auteurs wishing you "Good ev-eee-ning" — they're all present and accounted for. Don't dare touch that dial.
