Every so often I find myself angered again over how badly 3D animation is used in the anime industry, while smaller/older productions, and other industries, have no such issue.

Planetes (2003) had a 3D model space station.
It didn't do much, just spun around slowly, but it did so smoothly, unlike the choppy 3D attempts at anime, such as Berserk, Kemono Friends, and Batman Ninja.

Plenty of YouTubers can make some genuinely good animation.
Companies like Hololive do plenty for their music videos, with supreme-hag Marine being somewhat famous for this.

And outside the industry, the anime art style has been refined to such a degree as to make people doubt themselves at first glance if what they're looking at is 2D or 3D.

I hate this stagnation when it's clear that things could be so much better.
