Most children (and adults) love movies. Movies can make us laugh, cry, jump up and dream. Movies bring many elements including story telling, characters, emotions, visualiztion, sound and others together.
Movies are a subjective expression of the writers, actors, camera-persons, technicians and directors. Often, there are layers in the expression of each of these players. Critically interpreting a scene requires one to go beneath the obvious. It requires one to go beyond just describing the scene, to explaining it. To use one’s imagination to view the scene from the eyes of the creator.
(The same arguments holds true for art, literature or music !!)
Teaching children to understand those nuances can be fun way to develop the critical thinking as well as finer appreciation of art. Not just art, may be of life itself.
