Scooby Doo

Scooby Doo
Scooby Doo opens using a dark atmosphere to set the scene of being mysterious or scary; but as it is in a animated style it is not too scary for the children that would be watching it.
Using the main characters as friendly or relatable to the children, gives it a kind of comedy effect, which also reduces the seriousness of the program, whilst retaining the mystery elements.
Scooby Doo has a lot of ambient music in the background, to help set the tone for each scene and enhance the mystery.
The location is almost always somewhere spooky, for example a ghost ship, or a haunted house or mysterious woods.
