If this movie makes me want one thing, it's to reread the comic. So there's that.
Major Mira Killian is a ghost (brain) in a shell (cybernetic body), and is a member of Section 9, which goes after more unusual crime. Events kick off as people from Hanka Robotics, whom built the Major's body, are killed off, and in seeking answers Major finds out more about herself and what went into creating her.
Okay, this definite has parallels to the comic, with origin mixed in (can we please just do a movie that just dives into the universe and assumes the interested audience already knows the origin? Especially superhero movies). And yes, although she is Mira Killian, there is Motoko Kusunagi, who is played by a Japanese actor... and that ScarJo is cast says more about the nature of the Robotics company that about whitewashing in Hollywood (although there is that undeniable aspect too). That said, I will also say I do like the casting of many of the parts, especially 'Beat' Takeshi Kitano as Aramaki. In the team we also have Batou, Saito and Ladriya... although she disappears from the movie halfway through, huh? Was there a scene cut?
