By now, the question isn't whether or not you have seen Star Wars: The Force Awakens, but rather how many times you've seen Star Wars: The Force Awakens?
J.J. Abrams film did what many feared was impossible: it really, truly brought Star Wars back. It may not be a perfect film, but for an Episode VII, coming a decade since the last of the prequels, it's the one the universe and its fans needed right now. It's also one that not only stands up to repeat viewings, but almost necessitates them - just one of the many reasons why it is (unadjusted) the highest grossing movie of all-time in both the UK and the US.
When you first see The Force Awakens - especially if it was a midnight screening - there's a whole lot of hype and excitement, and the film blows past at such a incredible pace that it's difficult to really take it all in. On second, third, seventh or whatever you're up to viewing, the picture becomes clearer, you notice more things, you appreciate it a whole lot more, and it makes far more sense when you're not a tired and emotional wreck.
Even then, though, there are still a few things you're left wondering - like what was all that business with Maz Kanata about? In some instances this is due to changes to the movie from initial plans, in others, mysteries are solved in the accompanying novel, and in a few, the answers are staring us in the face, whether we get that or not.
