Ghost in The Shell is a popular franchise in japan, it started out as a book, a manga* to be exact, and is sold in bilingual formats, the book is borderline pornographic at points but is till amazing, i'd suggest it for those whom are 17+, but the television show, also known as anime**, is top-notch, delivering the same complex sci-fi stories, all amazingly done and truly questioning good and evil. The violence can be unnerving to some, as blood does spew out of bullet wounds and those are shown as well, but nothing quite as graphic as one would see in a slasher film. Parents should watch with their children if they are younger, to both explain and censor, they might even begin to enjoy it as well. The Protaginist, Matoko, does wear revealing clothes, and every now and then uses her feminine wiles to aid in the assigned missions, but is still a great role model as she is strong, independent, and resourceful. The verdict would be to not let your children watch unless if they have a strong understanding of right and wrong, are young, or are very susceptible to negative influences. But other than that let you teens watch away, even watch with them maybe, after all the franchise WAS the inspiration for The Matrix.
