10 scariest TV shows of all-time
'American Horror Story'
6. "The Walking Dead"
Why it's scary: The very idea of a zombie apocalypse isn't exactly a comforting one, but what makes "The Walking Dead" truly scary is that it makes us care about Rick, Lori, Andrea, Glenn, Carl, Daryl, Carol, Maggie, Dale, Hershel, T-Dog and the rest before thinning out their ranks in all manner of heartbreaking ways. Every time one of these characters bites the dust, we feel it, and that is truly frightening.
Scariest moment: [SPOILER ALERT] For my money, the sheer emotional brutality of Lori's death made it the ghastliest moment of the series thus far.
