They introduced a topnotch 3D CGI tech to the legendary anime, so there's no question about its quality. But viewers may feel uncomfortable with the discontinuity between the new full 3D CG and the original 2D scenes. Story It's basically the same as the original one, but the change of Puppet Master's sex brought about slight changes in the voice actings and the atmosphere. Batou didn't show so much jealousy over the relationship between Motoko and the Puppet Master, and the fusion of the two gave a pure impression rather than a sexual association. Art There are two full3D CGI scenes, something similar to the OP animation of the S.A.C1. The quality of the two scenes were awesome in the descriptions of the optical camouflage, air bubbles, reflections in the water etc. etc. But nothing buffered between the neighboring 3D and 2D scenes. You see 3D CG Motoko in a scene and the next moment Motoko is now in 2D animation. I understanding these discontinuities that Director Oshii wanted to show us his partial idea about how ideal GiS looks like.

Sound
SkyWalker sound studio did a terrific job in the sound effects. They were particular about the differences in gun shot sounds. Each gun sounded distinctively different. The sound of Motoko's cyborg body torn up was so real that it gave me goosebumps.

Character
No need to mention the greatness of Motoko, Batou, and Togusa. I focus on Sakakibara Yoshiko as Puppet Master. I think this casting has a good and bad point. Compared to the original actor Kayumi Iemasa, Sakakibara's acting didn't give me much mysteriousness of the character. (Kayumi's low tone acting was perfect for giving an enigmatic impression.) Good thing was it got easier to grasp the idea of the Puppet Master's line "We are mirror images to each other." because Sakakibara's voice resembled Tanaka Atsuko's one in this movie.

Enjoyment
Before I watched this, I tried to memorize the contents of the original one as much as possible. It was so much fun to find changes in the lines and drawings. If you are fun of GiS 1.0, I strongly recommend to watch this remake. You will have a deeper understanding of this legendary title.
