Nice example to kids, and adults
Not all average adults are a good example for kids to follow. Adults need to show this kindness in daily life, in routine, not just talk about it. Showing this movie to kids might teach them better than an explanation gave by their parents or teachers.
About the animation: The opening part was a little akward. Try making it slower, and pick the key scenes that explain what your animation (or series, maybe) is about.
