>just digitally redraw some old cels but make the lines blurry and put on an off-white filter bro
This is like what you'd get if you told an alien who has never seen cel animation before to imitate it. But no one gives a shit because streams compress videos so badly that fine details like film grain, natural light, shading outlines, and the shadows layers cast on each other are blurred out anyways. Same situation as the upscaling grift in video games.
