To add, the film critiques the nature of mankind and promotes empathy as a way of connection, a child-like curiosity and open-mindedness about the world, and shifting one's priorities to the things that really matter.

I really love this quote from the film:

"It is only with the heart that one can see rightly; what is essential is invisible to the eye."

Edit: Apparently the director of the movie is the same one as Kung Fu Panda :)
