The biggest thing about these Chinese parks is that labor and resources are cheap enough to make the giant buildings and thematic buildings, yet they are never designed well. Sure there is a mountain range, but there is no means to address sight lines or any attempts to really "transport" you to a different time and place.
I do think thats a problem with all these "theme parks" across china is that they are trying to imitate a Disney Park rather than Disney who tries to imitate a real location, culture, etc.
