..."The Calusari" scared the living daylights out of me. As did "Syzygy." Oh my god. I was terrified of ever offending a mean girl after that. "Home" is creepy and gross more than anything else.
"Provenance" is easily the most terrifying episode of SPN. I mean: a haunted gothic painting, dolls, a creepy little girl with a straight razor, the porn motel room...best. episode. ever. Even if I couldn't sleep afterwards.
I LOATHE "The Kids Are Alright." It introduced Lisa, and her stupid kid, and was the beginning of the end of my SPN viewing.
