Not everyone - just some vocal folks. While I'm not a fan of some of the results of the art I also am not 'disappointed.' Like I have said previously - if he has found a way to create his art and then make edits/revisions to his liking that helps his throughput, bully for him. However, if he relies too much on AI without much editing, he risks losing copyrights on his designs. However, hopefully it will help him be more consistent with his character design, which has been all over the place throughout while he has been freehanding. At the same time, I don't even recognize the latest character preview. I guess it's supposed to be Mary? But it has some Gerda characteristics in the face/hair and some other non-Mary features. The AI may be doing a little hodge-podging which may cause even more problems in consistency.
You're probably not wrong. Same with the ass/thighs. It's the problem with it probably being initially generated by AI.
