Hurting it? It's the highest grossing movie in US history AND in the shortest period of time. 800 million in three weeks. Also, the third highest grossing in world history. It's also grossed more domestically than any two of the prequels combined.Yeah....bad word of mouth is killing it....
The reason Titanic, and then Avatar, ended up with their colossal hauls of 2.2B and 2.8B, respectively, is because they had very small percentage drop-offs from week to week to week to week to week, et cetera, for a long time. TFA performed great out of the gate, but it is slowing down so precipitously, that it will not follow the highly unusual trajectory of the two aforementioned Cameron films, but instead will follow the trajectory of traditional modern blockbusters, that have huge opening weekends, even huge first fortnights, but then they fizzle out at the box office.
TFA has another problem, besides fitting into this more common blockbuster box office trajectory, and that is the critics are turning on the film, and the bad word of mouth amongst moviegoers is catching up to the film. Every review, article, blog post, or other blurb about the film on social media is ripping TFA now for ripping off A New Hope, and ripping it off poorly, at that. People who haven't seen it are now happy to wait for the DVD (or not see it at all), and those who have seen it aren't seeing it over and over and over again, the way they did Titanic and Avatar.
TFA will not be the biggest movie worldwide of all time. It just won't have the legs to get there.
