Both seasons of Ghost in the Shell: SAC_2045 are on Netflix. They already released a recap/compilation movie of season 1 called Sustainable War, now a season 2 recap/compilation movie is coming for those too impatient to watch all the episodes.

Like the poster says, it'll be in japanese cinemas in November. No word on when this movie will be added to Netflix, but I assume it will at some point.

SAC_2045 uses CGI animation so it's been pretty divisive among GitS fans. The story is solid though if you can get past the animation style.

If you aren't up to date on Ghost in the Shell, there's also a 5-episode OVA called Ghost in the Shell: Arise which came out in 2013. Those five 1-hour episodes were recut into ten 30-min episodes, called Ghost in the Shell: Arise: Alternative Architecture. Those ten 30-min episodes were then recut into a single movie, called Ghost in the Shell: The New Movie. All iterations of that show are streaming on Crunchyroll, so you can watch it however you want!
