It's a Disney movie, what did you expect? There's always an underdog, a fairy tale ending, and all that. The movie are meant to sugar coat the world to make kids think that the world is all happiness and desserts. The old fairy tales told to children before bed were gruesome, full of death and unhappy endings. The original Little Mermaid story ended with the prince marrying someone else and she was turned into seafoam. While she was human, walking felt like she was standing on knives. In versions of Cinderella, the stepsisters each cut off a piece of their foot to try and fit into the slipper.
