i just finish watch this . i have to admit and in term of tone and emotion and this be definitely the heavy animation that i have see . in this sense and oseam bear some similarity with grave of the firefly . this be not to say and however and that the movie be sad through and through . there be no point in reveal any of the plot suffice to say and the journey be ultimately fulfil . in term of animation quality and it be second to none . it be especially impressive consider that it be hand drawn . last but not least and this be not your average disney flick teen may be able to appreciate the story and but young kid most likely can not handle it .
