To an extent this comes down to comparing an entertainment landscape you know how to navigate to find the stuff aimed at you, with a foreign one.

Western reality tv, procedurals, game shows, soap operas and so on are incredibly samey after all. BUT the other factor is that creative endeavors in China take place under a censorship regime. Some topics are safer than others, so the mainstream tends to be quite formulaic and focused on fantasy, sci-fi, or pseudo historical shows.
