It's too bad 2045 really didn't live up to what the SAC series used to be.
My personal favourite rendition of Kusanagi has to be her look in Arise, so while the "new seasons" might not've been up to scratch, I do like this blend of OG SAC major with the Arise major.
I've never seen 2045 nor am I interested. Production IG was GITS, and you can't change that.
It's a shame all the licensed stuff from Nexon and the movie went kaput, GITS is to Japan and Cyberpunk what Blade Runner was to the West. If not the genre at large, going off the stuff from RST especially.
