Behind the bloom of the production of animated documentaries lie the changes of the range of thse sense of reality animation can capture. Some animators, like Yuri Norstein and Caroline Leaf, have been finding that animation is appropriate for experessing a subjective view toward the world. The worldview seen in their films focuses on a narrow world around them and because of its narrowness implies the existence of the world that never belongs to their world. This sense of reality has something in common with animation documentaries when these films try to focus on realities of outsiders or minoroties.
