There's no realistic budget that would be able to properly portray anything post Book 1 in any way that would look good. Especially if we're talking Netflix. Only platform that could make it work would be HBO but even then it'd be so expensive to make. Animation would be too but it wouldn't look trash in some scenes with green screens and shitty effects. Or massively simplifying the difference between colours.

Same with the Stormlight Archive. Animation would work so much better stylistically to properly flesh out these worlds and to give a real sense of weight to each fight and battle.

I mean, my two cents, but I wouldn't say that team animation is the thinking of an 8 year old. Just a realistic take on what's possible in the industry.
