Just to qualify the anticipation a bit: Douban, the online site referred to in that tweet, is a pan-Chinese site, subscribed to by local and overseas Chinese as well as any non-native Mandarin speakers. It's foremost a cultural user-generated receptacle for criticism and discussion of books, music, movies, and tends to be favoured by denizens of Shanghai, Beijing, Shenzhen rather than those from tier two cities and below (where a big chunk of moviegoers come from).
So, while it's an indication of Chinese interest, it's not quite representative of the moviegoing public in China. Saying all that, BvS should be a big draw over here with audiences ever-keen on Hollywood blockbusters.
