Though any amount is far more than I'd like, there was surprisingly little "human filth" to be found in this part of the series. The focus is instead exactly where it should be, with dragons that are really coming into their own, reaching their potential both in how they act and in how they're presented, and battles that are depicted wonderfully.
I must also note that, while the author has raced through a lot of potential action, seeming to only want to depict that which was particularly meaningful, the effort to take a shot at several important issues that the world is still facing is still obvious and, I believe, largely successful.
