You cannot produce "this kind of content" without a lot of manual work. Think a character that has like 3 pixels per eye, and one for each pupil, and that one pixel moves 5 times during the dialogue animation, at exactly the right moment so you know what it expresses. You don't get that by averaging high-res 3D content. Now someone can see this as a challenge and make something that will fool some people, for some time, of course. There is so much pixel art to steal for that purpose, after all. Just like you could do with the masters, who expressed a whole lot with a few scribbles or strokes of a brush... but even trying that means not getting it, at all, and someone who doesn't get it will not produce anything worth looking at, ever. It's like hearing sex exists and figuring out ways to realistically stain your sheets so your friends think you had some. Why even, ever.
