Fisrt of all, this movie will not likely appeal to those who only watch anime for the big hair and eyes that are the current style. The animation is realistic and graphic, closer to Miyazaki or Venus Wars than more stylistic films like Ninja Scroll. The soundtrack is deffinately distinct and can take some getting used to, using mostly voices and a few instruments.
The movie is hard to describe. Apart from the mixing surface plots involving the biker gangs and "blue kids," there's plenty of material to play with for the philosophically inclined. Themes like existance and the nature of humanity show up beneath the main storyline.
I gave the movie 4 stars because I feel it deserves it from a story and intellectual stand point. The animation, although plain by current standards, is smooth and detailed. The storyline can be confusing and most people I know needed to watch it through a couple times but for me the big shortcoming of this edition was the new dialogue. I felt that the original recording was sharper and fit the movie better. It feels like they dumbed it down for the new one.
