Improves on the first season in pretty much every way. The animation is a little more consistent, there's more action, and the story is both deeper and better paced. Political intrigue at the higher levels of vampire society, dark ambitions fueling the leaders of the Japanese Imperial Army, and double agents on seemingly both sides all combine to create a setting where it's difficult to see things in terms of simple black and white.

That all said, while the show is showing more potential than ever before, it has a ways to go before I can really call it "great." The animation may be an overall improvement on the last season, but it still blatantly drops the ball at times. The scale of power between humans and vampires is also being handled a little poorly, in my opinion. At this point, the humans simply cannot be expected to win this war without an absurd power boost that would be out of character for the show.
