The 13 Scariest TV Episodes of All Time
Supernatural, "The Kids Are Alright"
9. "The Kids Are Alright," Supernatural
Sam and Dean find themselves on the trail of a changeling demon, who steals children from their parents and burns them underground. The frights are of the straight-ahead "scary stuff appearing unexpectedly in mirrors" variety, but here, it's children, and they're burnt and mutated. A classic horror trick, done very well here as you can see in the photo.
