I wasn't too sure about this one. The first act is a bit slow, for the most part, and I was just starting to think this had been a bad investment. But then . . . .
I was shocked out of my socks by the great humour, even Looney Toons comedy that soon developed. I was just getting used to this surprisingly funny movie, when it took an entirely unforeseen turn; relevant, contemporary, typically dirty politics.
What is revealed, in a cartoon, of all places, is the basic social design used by humans who have amassed far too much power. They come to control the one, singular, vital resource upon which all humans depend. And this is what makes those powerful humans so dangerous. In the case of Rango, it's water -- a fitting analogy for money, which has been controlled by a handful of powerful families for a great many years. But I think that by now very few are ignorant of this fact.
In this film, those power-families are represented by the tortoise mayor of the town Dirt. This mayor has managed to manipulate matters so that he owns exclusive control over the water that was meant to flow freely. An apt description of the financial situation we all face today: the fact that money is criminally manipulated to fool everybody into thinking they have to bow down to a few powerful criminals in order to survive, when the true resource is cooperation between everyone. And that's the one characteristic this powerful mayor of Dirt can't allow to get out of his control. He must keep everyone stupid, ignorant and in despair, while feeding them that tiny bit of false hope every day.
There's a great deal more meaning to be enjoyed in this film. But I don't want to spoil the revelations or the surprises. Just watch this film and see for yourself.
