This is a anime with a intriguing idea, and interesting premise and start, that doesn't really feel like it goes anywhere. Which is a shame as there is so much to like about the world, I liked the idea of the earth essentially being a clock work planet now.
Problem is this is a example of a great idea hindered by poor villains and lack of feeling of gravitas. I never understood the villians goals, or their reasons and what their final plan was supposed to do. which made the final moments confusing.
I would say watch a few episodes to get the feel for the anime and the world, but if you watch more, be prepared to possibly feel unfullfilled.
