Inside Out (《玩轉腦朋友》), Disney-Pixar's animated feature, has broken a few rules. Unlike many animations, it is neither a grand adventure saga nor a sweeping fairy tale about a princess awaiting her knight. Instead, we can easily identify with the story through the characters - Riley, the 11-year-old, her parents, as well as Riley's emotions: Joy, Sadness, Fear, Disgust and Anger.
