Without the bias of having read the manga, I found this film to be refreshing. It was unique and interesting. Film almost never replicates a book accurately. There just isn't enough time. It has to be pared down into a manageable time frame. With the expense of this film, it also must have mass appeal. I think those decisions were probably intentional. While I understand your disappointment in the changes, I think most viewers will appreciate this film on its own values. I loved it.
