Are mad? Uninformed? Or Both?
The character is not meant to look Asian. As a long time rabid fan of GitS your article gives me the vibe of some buzzfeed writer jotting down some stuff while being high on excitement of something he/she barely knows about.
GitS goes way deeper and you are already high on the shallowest levels.
I wanted to see a live action GitS starring Johannson since the day I saw Lucy (2014)
She was the perfect person to play the role and I haven't seen a single person from Japan complaining about the casting. There were some YouTube videos on that too.
