being an handdrawn animator myself I do not forget. Japanese animators are the best, no doubt. I love the work of mr. Leiji Matsumoto. most intense work of him I ve seen is The Cockpit. but all his creations are deep and intense.
I doesn´t know the Nibelungen reference but next time if I have chance of follow all the Harlock sga I will check the similarities or storytelling quotations about.
thank you for the information and for your nice comment. you are welcome
