Also for fans of the universe, the new GITS Arise alternative has just aired and it dives straight into action, while it isnt stated anywhere, it feels like a direct sequel to the Arise movies that aired last year...
It also features a different style than the original movie and the SAC series, it also brings some character changes in the designs and some voices, but at it's core it has the very same spirit of the GITS universe...
Edit: Actually i just checked the 4th movie and the new anime starts after the 3rd movie and episode 1 and 2 of the anime will cover the events of the 4th movie...
Edit 2: You can skip the movies and jump straight to the anime, although movie 1-3 are in fact a prequel to the anime they mostly deal with the formation of the Major's special unit and their individual recruitment into the organization, particularly interesting to get a little background into everyone, the anime skips this building and jumps straight into the action, the anime is comprised of 10 episodes...
