Submitted for your approval: Every episode of Are You Afraid of the Dark? is now on YouTube. Relive the spine-tingling moments of your youth as many times as you want. Which was the scariest episode for you? (Please don't post images from Tale of the Quicksilver in comments.)
No show has consistently terrified me as Are You Afraid of the Dark? did. There are two episodes that distinctly stick out in my mind and still give me nightmares. One involved people being trapped in paintings and then the paintings being burned and the people inside them burning to death. The second involved what looked like a bloody, raw, half-decomposed wookie in a school swimming pool trying to eat two children.
Add those to the episode of Buffy with the Gentlemen and you have 90% of my childhood nightmares that have stuck with me into adulthood.
