In a child’s mind, this is how things work. It’s a simple approach, one that’s easy to understand. The good guy tries to stop the bad guy. The good guy does the right thing, the bad guy does bad things. It’s a child’s perception.
It was my perception–until I saw Indiana Jones and the Temple of Doom.
