I find this a little messy, plot wise and culture wise. As a film, it reminds too much of a TV cartoon - I need more art from cinema. I love the concept of bringing these discussions to animation world, but it has to be done as well as the other big animations. To stand a point, wider is better.
A perfect predecessor to "The Good Dinosaur" in that it features an amazing color-scheme, and some seriously intriguing animation despite the fact it can't figure out a really interesting or clear story to tell.
