Although the original is a comic for boys, the film director is Mr. Otomo who dealt with famous "Samurai" period drama series, so you can expect it.
In Hollywood, American comics, such as Spider-Man and Bat-Man, are finished in the very high quality entertainment work.
There are many wonderful contents in comics of Japan, too.
I think that the movies of the comics original which were strongly conscious of the release in the world should be sent more in Japan.
