Like this
1: A Princess (DUH!)
2: Songs
3: A Villain
So on

Remember that countdown we did about what each princess in the line up need to have or do to be in the line up? Well this countdown is like that, you can say needs to be made by Disney and not Pixar, needs to have a prince, needs to be a fairy tale, needs to have music, and so on!

In no particular order:

1. A concise and cohesive plot;
2. A Female Lead;
3. A Villain with good motives;
4. Songs;
5. Score;
6. Useful sidekicks;
7. Magic;
8. An interesting setting;
9. A Moral (Lesson);
10. A Happy Ending :)

^I agree exactly what he said, but also

1. Lead must be human
2. Character development

1. Lead role be human
2. Good plot
3. Good songs
4. A great villain
5. Character development
6. A lesson to be learned
7. A plot twist

I might come back and add more. (:

^I almost included character development, but there was no room.
