That makes a lot more sense. I wonder how much WOM from America, Europe, etc means in China in the more internet-friendly age. Anyone with a computer in china can go look and see that a) it's breaking sales records and b) it's crushing reviews.
I think this is viewing the film through a very western lens though. The film has been out in Hong Kong, Taiwan, etc for weeks. I think your average Chinese moviegoer is going to check out reviews and buzz from those territories over what it's doing in North America or Europe. Star Wars hasn't broken many records in Asia.
