Just watched Stuck In The Suburbs. Typical Disney movie. Simple plot, happy ending. Upbeat themes. Kind to children. Some moral themes that they get about right. Happy people succeeding. Good music.
To describe the same movie from a more typical adult perspective, and also the perspective of younger people who want to be/act grown-up, which is most teens: the movie had an absurd plot where some silly teen girls get a rock star's cellphone, find out his secrets, and become friends with him. The plot was obvious from way out, the villains were retarded and incompetent, and there wasn't really any point to the movie. Yay, they met a rock star, so what? Who cares about that? There was no action.
And so it is that most movies feature conflict, strife, and tension. Unhappy people and serious problems. Without these most people get bored. But they are missing something major: sure, if something bad happens to you, it's important to confront and solve it. But most of life is not like that. You don't have to first become a victim to succeed. A good life mostly consists of just what Disney movies show: people with no particular problems succeeding at something that, though generally not very "important", they enjoy. (Or at least, the problems most people have don't pervade their life, they're just subject-specific.)
What to do when you're *not* a victim is a far more interesting and common problem than how to fight. And it's a lot harder to write about, so few people even try.
Try to think of a movie where some *parents* just have a nice time. It's not so easy. Even something like City Slickers, they all had serious problems. They were basically trying to deal with mid-life crises.
Or think about how many love stories don't make it look like the couple is about to breakup forever a couple times before the end? Or think about why love stories almost always end when the couple gets together.
