How to Train Your Dragon (2010)

Toothless has to decide whether the boy approaching him is another threat, and the scene gives that decision time. The animated dragon's wary expressions and changing distance make trust feel reciprocal. Once flight becomes possible, the exhilaration comes from two vulnerable bodies learning to work together. Choose the 2010 animated original for that wordless relationship; its creature is most appealing when he remains an independent partner, with danger and injury still part of the adventure.
