There is not much to say. 2.0 is an unnecessary, invasive and generally destructive "remaster" which violates the tone, breaks the immersion and adds strange 3D scenes, attempting to unite the original with the sequel in style, all the while their stylistic differences were so important to highlight the advancement of the story.
Avoid this and watch the original 1995 Ghost in the Shell.
