At the same time as thinking that, though, I was also sitting there thinking "Oh dear god this is going to be the thing that terrifies a whole new generation of small children."

For me, it was Flotsam and Jetsam. These kids will never look at shadows the same again.

Granted, children of really geeky parents have already been shown Silence in the Library and Forests of the Dead, so they're terrified of shadows anyway.
