After watching this film, I managed to grasp onto the simplest form of character progression in a movie. Although the movie was animated, I felt that after watching the simplest of parts, character progression is hard yet easy to notice at the same time. When you can visibly see a difference in the character’s appearance or tone of voice, it is evident that they have aged. When you hear character’s change of opinion due to maturity, it’s easy to notice how they’ve grown through experience and learning. If you take those two elements out of the equation, it is harder to notice. I think it is important to look for ways the character has changed (not physically or through narration) but through dialogue and interactions with other characters. It isn’t direct but it could be important to look for. Who knows, maybe you’ll find something else in your search.
