>The anime has some problems; namely pacing and the density of narrative.
I wouldn't call those problems, in that those are the hallmarks of the entire Ghost in the Shell franchise: relatively slow pacing, extreme density of information/concepts, and lots of exposition. If you're getting into a GitS work either you accept those and enjoy it or you don't and have a bad time. It's like saying Naruto has too much fighting.
Otherwise, I completely agree about Stand Alone Complex, and to me Ghost in the Shell: S.A.C. 2nd GIG was even better. It's astonishingly prescient, it seemed to absolutely nail how the 2016 election would go down to having a Steve Bannon figure who uses manipulates the media and intelligence information to achieve his goals.
