well, I agree with that.
But anarchy is still not tyrannical. It's simply bad word choice
The film can have whatever themes it wants...it's all about execution, and having the theme evolve naturally from the story... or have them work together in concert.
That's not what has happened here. Nolan constructed a complex narrative, but the story underneath it all is paper thin. And the themes of economy were not well-realized. If he really wanted to tackle the inequality issue, he would have had Bruce Wayne be the villain, and would have had people rise up against people like him. Imagine that. Bruce Wayne is the villain and the hero. But, he took the easy was, tip-toeing on these themes rather than confronting them.
