This reframes Disney's classic appeal principle through a character psychology lens. Instead of just "make it cute," it asks why anyone would watch this person, then connects all twelve animation principles back to personality expression. The practical bits are solid: questions about how a character walks or uses their hands, the five types of appeal (sympathetic to menacing), and debugging steps when characters feel generic. Most useful if you're stuck making characters that move correctly but feel flat. The mental model of treating timing, arcs, and squash as expressions of inner life rather than technical requirements is the real shift here.
