I guess this adaptation is based on the Manga/Movie rather than the SAC series? I would have thought that the SAC series would translate better into the live action field, but then again, I guess the manga has a deeper tone to it which provides an extra level for the film to portray (of course, they'll probably just go for all out action and ignore this anyway...)
I have low expectations of this, as I generally do of US remakes or adaptations of Far East media, so actually won't care if it's good or bad.
