A terrible mix including the myth of Frankenstein (there is even an Igor), 1984 and the Nazi holocaust and an ultra-violent video game a la Final Fantasy, cooked for advocating in favor of world peace (?). Also, terrible monologues, the typical Japanese over-drama and an OST to be burnt. Just giving it some points for its aesthetic which I don't like but I can see the effort on it, as it was also done in "300".
This movie is one of the main reasons I decided to study film in college. It uses, CG, matte paintings, green screen, and claymation to do all the effects. It's a very stylish take. The story is very powerful. Each time I've watched the movie I am always left thinking about the plot and it's overarching meaning. I highly recommend this film. Just have an open mind to the world and directing choices.
