The film from a technical point of view is perfect. Impeccable animation, direction, and script. A great merit is the management of the most important scenes, such as that of the final battle, and the various ost inserted at the right time and in the right scenes, which arouse only summers and emotion in the Viewer.
What can I say, a perfect film to say the least, for one of the best anime of the last 20 years, and the best battle shōnen ever.
