Fear of the Dark is a cool movie.
It is a scary movie, but if you're not a fan of the genre don't discard it. It appeasl a lot to our childhood.
It deals with a little boy's fear of the dark. He sees things that are not there in the light. Shades, shadows, shapes. Just like we all do. But we do know that it is our imagination that turns those shapes, shades and shaddows into living creatures.
In the movie they are real. The dark exists as an entity, as a different world. Our belief gives it power.
