I get giddily excited whenever something new comes out of studio Ghibli. Miyazaki, especially now that he has officially retired from animation, should be honored by the legacy of brilliance in animation he has left behind in not just this, but all of his films. I also believe that it is important to note that many of his movies center around a theme of ambiguous sense of rightness from both sides of a conflict. This is important in my mind, because I get the feeling that Miyazaki wishes to present the audience with the fact that in every conflict, there are multiple sides with their own concerns, motives and justifications. Sounds like a social commentary to me, in addition to a being an animation masterpiece. I agree that it should be preserved, for both its caliber as a film, and for its message of childhood wonder and reverence for the past.
