Scariness tickles a safe child in a fun way, but it deepens real fears in an unsafe child. So know your audience. Give the option of leaving to any child who doesn t want to listen. Kids get enough of that at the movies. Know your child.
Some kids find scary stories disturbing, even at mature ages.
But that's a decision only you can make. So good luck. The younger the child, the gentler the material should be. No one dies. And of course, evil characters never win.
