Yes, I don't know what would possess an American company to demand CGI from a JAPANESE 2-D ANIME CO-PRODUCTION STUDIO. Sheesh! Knights of Sidonia was so stupid. You'd think Netflix could do the simple math of figuring out Japan needs to do traditional cell animation.
Why not just have them do what they're best at? 2-D cellophane anime! Toonami gets it (FLCL), Crunchyroll gets it (Canon Busters) Netflix is STARTING to get it. (Production IG)
Asking Japan to "Do Pixar" is like asking Pixar to "Do Production IG" It will result in CRAP, they're out of their element.
You've got to do what you know how to do professionally. You gotta do what you're good at. Your expertise and comfort zone. Why disrupt that??
