Meh. I think the anime crowd needs to take a good look at why there have been no faithful translations of anime to live action or for that matter successful anime to live action crossovers. I think it has to do with the nature of anime as animation and how a lot of things you do in a cartoon don't look or feel right in live action. As such, they need to stop being over-purists and accept that while live action can be based on anime it really cannot be a completely faithful imitation.
In the case of this film, just take it on its own merits and stop trying to shoehorn it into the anime. When doing that it is pretty good. It gives you a cyberpunk feeling setting and tells us enough about the characters so we can relate to the main ones (Major, Batu and Chief Aramaki - by the way I loved Aramaki's line "don't send a rabbit to hunt a fox"). And we get drawn into what starts as a murder investigation and turns into Major realizing her past is not what she thought it was.
Anime fans do not seem to think that anime is cartoons. But that is 100% what it is. No, it isn't special because its anime, its just foreign cartoons. But if you tell an adult anime fan that his anime (I do not see this phenomenon with any females) is "cartoons", he will get indignant and go on about how it is art. Whatever the case, you can't take cartoons and turn them into real people very easily. If they spoke and moved and looked like their anime characters, they would look like this:
I am just not a fan of anime at all.
The only Japanese anime I liked was Speed Racer, Kimba, Gigantor and Neon Genesis Evangelion. All but Evangelion were faves only when I was a kid.
Neon Genesis Evangelion was great to watch stoned, otherwise no.
