I don't know about that. There was a good amount of familes that went (news channels interviewing families on youtube) to THG. What really stands out for THG series was that the first movie drew in more people over the age of 25 rather than younger than 25. That means better legs when you can draw in an older audience. Not to mention the first film showed that it is a 4 quadrant film, meaning that all groups of people (older than 25, younger than 25, males, females) will be attracted to watch it and enjoy it (most did). Unlike Twilight, and perhaps HP, this is as close to a 4 quadrant film as you can get. Granted, theses were domestic figures, but I think the same can be for OS as well.
