> Frankly, we have little real idea what's psychologically appropriate for kids.

You must be joking. Look at parental guidance for movies and games for example. Violence is good and appropriate. Just show no blood. ( Harry Potter). Sex is not good except when in Disney movies and preferably between a prince and a princess. Scenes of normal life are borring just like story costruction. Children must learn that they have to reach the goals as fast as possible, no matter what means are employed. And did i mention violence ? Maybe they don't have it at home but it must be introduced somehow in their lifes. They also need to speak more hysterical. TV and politics have shown that if you speak in normal tone noone will listen to you.
