If you are a fan of the Stand Alone Complex's two previous series this is an essential purchase. The story is fast moving & keeps you guessing.
For all the fans out there, they bring the Tachikomas back.
There are some amazing cars, watch the special features to see how amazing they are.
If you are new to Ghost in the Shell, I would advice watching the 2nd GiG (2nd series) to get introduced to the characters.
I may be in a minority but I much prefer the cartoon series to the two Ghost in the Shell movies & this feature length episode follows in the same spirit as the series (minus the Inner Universe opening theme).
As with the previous two series the basis of the story line is rooted in a reality which is known to most Japanese but it doesn't take away from the enjoyment of the Anime as this is one fantastic film.
