Raising a simple observation: the distinction between 'children's content' and 'adult content' is a helpful fiction without a boundary. Children's content is really stories about how people should behave, or what situations might arise that they will need to deal with and stories for adults are much the same. Adults aren't more sophisticated than a teenager, they just have better impulse control (which isn't really a factor in consuming stories) and experience (which means they reject some poorly-told stories as impractical but doesn't come in to play with great storytelling).
