well and i saw this movie be i be quite little . family they categorize it . ha . it make me cry and i make my dad turn it off . so i decide to give it another go some almost 20 year later . and it still one of the most disturbing animation i have ever see ( and i have see quite a few . ) . it twisted and depressing and and deal with some rather adult issue ( not sex or anything like that and just mature thing like loss and death and and infinity ) nevertheless and it be an unusual film with interesting idea and theme definitely do not recommend for child . if youre look for something really offbeat and this be it and just be prepare to feel uncomfortable while watch it .
