So...
I'm not gonna say he's wrong. Ultimately I don't think he 100% is.
However, when it comes to Asian fantasy, and this is coming from an outsider's prospective, it becomes difficult to meaningfully take in criticisms as set dressing and character design being distinctively historically Asian, or picking and pulling from Asian mythology for certain things and complaining that doing as such is racist. Like, I feel like his subtext here is that the only middle ground to be had is a modern setting with an all Asian cast doing non-descript things extremely well or else the film is either white washed or sinophobic, because of Asian depiction. Like, as if the only good story you could tell with an Asian cast on an Asian slant is something like Space Sweepers (which is Korean, I know) where the core cast is all Korean, but the remaining cast comes from a wide variety of cultures and it's about how this Korean cast deals with their specific problem in a world devoid of traditionally Korean history or culture. I don't know if I can get down with that.
The whole thing reads like, "white people reciting asian problems through jokey ha has is inherently racist", but if that's how you feel, how do you ever make an asian film outside of asia without being racist? Furthermore, if an asian film made in asia plays into the tropes that we see in Shang Shi, is that internalized racism? Or is it fine when they do it like when I use the n-word?
I don't know. He's welcome to his opinion, and there are elements of this where I could be like, "I mean...sure, okay." But...like...if you feel this way, how do you feel about the dozens of chinese and korean period dramas on netflix that are 100% asian cast, crew and culture that are just as hollywood blockbuster focused as Shang Shi is? Where's the line? How do you define it?
