I had no preconceived notions going into this series. It was a random Netflix stream and I had never heard of the series. I was hooked from the beginning - a rarely explored historical setting, jaw-dropping fight choreography, high quality animation, serious plot but not overbearing - it was great. We're so jaded as otaku into expecting the usual WWII whitewash from Japanese mass media - but it reads pretty true to events (aside from psychic powers and the narrative conceit of the Japanese mysteriously inventing a protypical A-Bomb). Unfortunately, the crazy choreographyof the fights disappears quickly and true to most anime, the script loses its way and can't seal the deal in the end. But it is still a great achievement and shows much promise in terms of Japan dealing with its controversial past.
