The main problem with the graphics, apart from anything else, is not that they're "not detailed enough", because there are many great games with simple graphics, such as Breath of the Wild, among many, many others.
The primary problem which I see is that the character models have perhaps the worst motion animations I have seen in a "serious" release for a while. Heck, Mr. D's (I'm not getting into the various spellings of his name) body is completely divorced from the motion of his arms, which are divorced from the motion of his head in the trailer. The only way I would be able to accept such awful animations and, top be frank, plastic-like graphic quality with nothing original to tie it together in a modern game would be if extreme character customization was offered.
However, from what I have read, this does not seem to be the case.
As more information has come out, the game has dropped to the murky bottom of my "games to check out or recommend" list. I'm sorry, but, as an avid player of many games myself, I simply can't accept those animations, or the graphic quality in this age, as nothing original has been done.
