Here's what JJ Abrams had to say about the title
not that it cleared anything up
" The title feels like it’s the right title for this movie, and I know that it’s provocative and asks a bunch of questions. But I think when you see the movie, you’ll see how it’s intended, what it means. But in the flow of titles, this movie had a very weird responsibility. It had to be the end of not just three movies, but nine movies, and the idea of having to incorporate the stories that have come before strangely is the story of the movie. Which is to say it’s the characters in the film inheriting everything that’s come before in previous generations, whether it’s sins of the father, whether it’s the wisdom that they’ve acquired. And the question is this new generation, are they up to the task, can they stand up to what they have to? And so in a way, I feel like we coming into this movie have inherited a lot, and the question is can we do it? And that question we ask ourselves every day."
