YOU HAVE GOT TO BE KIDDING! Really? Yes I am being sarcastic because this is ridiculous. You are being unreasonable. I think when tens of thousands of people wait to go into a store it can be generally assumed that most bought something and sales were high that day. That is reasonable. I have never heard of any situation that was otherwise. Find a news story that talks about low sales or find anything that gives any indication that people didn't buy that day. If you cannot, then the reasonable rational assumption is that PEOPLE LINED UP TO GO INTO A STORE TO BUY THINGS. Do you have any evidence that the reasonable and rational normal assumption is wrong? Let's hear it.
For 4 days there were continued long lines of an hour to get inside. I haven't read anything since, but store attendance is like movie attendance: Patterns of behavior are predictable within normal ranges. For example, whatever a movie makes on opening weekend, whether $10 million or $100 million, it is probably going to decrease the next week by anywhere form 40 to 60 percent. $100M movies never drop to $2M and $10M movies never jump in the second week to $50M. Same rules apply. The first day and week after a store grand opening gives some indication, within a range, of performance over the near future.
Obviously we don't know long term what will happen. You have to take everything one day at a time. But in the area of brand recognition and public acceptance, historic crowds at a grand opening is never bad. That generally portends good. Every news story I've seen is saying the response suggests a high interest in Disney among Shanghai's population. That is a reasonable conclusion. Unless everybody stood in line for hours to go in a store they didn't care about and not buy anything. That is not a reasonable assumption to make based on any rational approach to how sales work anywhere, including China. And remember, this is China with an enormous population and Shanghai is China's biggest city.
I am not yet predicting massive success, but so far the facts are pointing in the direction of success. There is no other reasonable way to logically interpret the facts. Just like the facts about the Tomorrowland movie are pointing in the direction of failure, even if the jury isn't in yet and it isn't "historic" in level. I can accept both - one I like and one I don't - but both assumptions are at this point supported by the facts.
