It's worse than that, from what I've seen in trailers. This is a remaking of the original GITS movie, except with the American "action movie" formula applied. That means a lot of the subtle subtext will likely be missing, and the huge subtext at the end might be completely lost, which would make the Major's battle with a tank completely pointless (hint: she felt if she couldn't beat the tank she was no better than it).
Then again, they might be keeping back the best part until the release, and it might be surprising. Either way, the movie is worth watching at least once (not necessarily in theaters) just because of the visuals, and because Weta is involved.
