Why the villain Ronald McDonald?
I think that the animators chose Ronald because of the reputation McDonald has with its junk food which is not healthy at all. The way that Ronald was shooting without mercy in the movie describes exactly the way McDonald keeps producing not healthy food thinking only in the profit.
What is the message?
Not only McDonald, but also many companies are thinking too much in the profit of their sales instead of what is really good for people, and the earth. As the outcome of what is big companies are doing now, the world could end just like the movie showed us, ending with the people and environment destroyed.
