Parenting 101:

......................I'll have to ask my kids how well we did:

I don't believe in playing down to children, either in life or in motion pictures. I didn't treat my own youngsters like fragile flowers, and I think no parent should.  Children are people, and they should have to reach to learn about things, to understand things, just as adults have to reach if they want to grow in mental stature. Life is composed of lights and shadows, and we would be untruthful, insincere, and saccharine if we tried to pretend there were no shadows. Most things are good, and they are the strongest things; but there are evil things too, and you are not doing a child a favor by trying to shield him from reality. The important thing is to teach a child that good can always triumph over evil, and that is what our pictures attempt to do.
