This movie is one of the most creative films I have seen. Some may think the content is dark, but I did not see it like that all. It is simply how life is. It's message is simple. Better yourself and the world will be a better place. Or as and other man once said. Do unto others as you would have them do unto you.
I will say, however, that the characters may scare some younger children. But, it really isn't a children story
