I expect it to be a bit of a mixed bag.
I feel like the acting will be done up too flashy for the more brooding noir story style that GitS is, and instead the movie will be heavy on action and special effects. Whch in some ways is both a Pro and Con. The original ghost in the shell anime is perfect the way it is. It doesn't need to be redone. So having a different flavor of GitS, let it be it's own thing.
But we have to be realistic. we are dealing with a celebrity actress and big budget movie. we are not going to have the same level of invasive and raw story and character exposure as we can get away with in an animation. The scene at the end with the major stripped to skin in the sprinkling water desperately trying to tear a tank apart with nothing but hands, and muscles tearing under the skin and limbs shattering and tearing away. It will be SJ in a specially designed suit with a simple limb ripped off or cut in half.
By the same token though I fully expect it to be a visual feast for set and prop and costume design fans like me. There is a whole universe of beautiful story and background, fully fleshed out. I can't even wait to see a live action cyberbrain and prosthetics.
I'm sorta scrooged that they slapped SJ into the lead role, it's a major wtf were they thinking kind of thing. It doesn't even make sense. You have to actually try harder to come up with that as a possibility than any option that would make way more sense. That and you'd have to be completely disconnected from the fan base and have never really experienced the movie to make a choice like that. It's likely to be nagging at me as I watch the movie, like watching Bruce Willis starring as Lara Croft in the next Tomb Raider movie would, taking me out of the flow of the story because of the incongruity; but I will probably still go to see it.
