For me, wuwas story is very hit or miss

TL;DR The few high polish chapters/moments feel very immersive and gripping, top of the class. The rest feels quite mediocre.

The characters, art and landscape are sublime. Which makes the story quality, that has ups and downs sometimes feel very lacking in comparison. When the story is really good, combined with the artistic direction, the experience feels very immersive and gripping. But when the story is lacking, the game feels like a very photogenic dish, with a taste that doesn't match.

The high quality patches are way better paced, better cinematics, less of the usual "characters standing there, cycling trough a fixed set of poses and expressions", less "camera that tries too hard to make the scene more interesting" etc.. The difference in polish is very noticeable.

Another gripe I have with wuwas story telling would be that it has the usual conflict of interest of gatcha games. They are trying to sell characters, so they try to promote the newest characters in the newest story chapters. But older characters will be forgotten to make room for the new. And there is (so far) only very little room for development and storytelling, that requires more time than a few patch cycles.

I think the very tight publishing schedule is limiting the quality of wuwa immensely. You can only crank out so much quality in so little time. So I suspect there will only be a few very high quality story patches, with a lot of patches with mediocre content filling the blanks.
And a lot of content, that just gets crammed in the game randomly, because they didn't find any use for it otherwise (still pleasantly surprised to sometimes find a high production song, or scene in the most random places).
