I don’t like scary shows, which is why my friend Eva specifically wrote “not scary” in the IM she sent me insisting that I watch a clip from last Thursday’s Supernatural season finale. She knew I’d enjoy seeing Dean (Jensen Ackles) and Sam (Jared Padalecki) sing “Wanted Dead or Alive.”

Me: They used the best part of the song!
Her: I know!

Combine this with the show’s appearance in our gallery of gratuitous TV moments, and I’m seriously considering catching Supernatural in repeats. But if I do, will I ever sleep again? Eva says she goes completely cold with fear at least once an episode: “There is often whimpering. On rare occasions, tears.”

So how scary is this show? And where does it rank among TV’s greatest spooks?
