10. The Chosen One Narrative
In The Phantom Menace, it was revealed that there would be a so-called "Chosen One" who would "bring balance to the Force", ridding the galaxy of evil. Qui-Gon Jinn, and subsequently the Jedi Council, came to realise that a certain boy from Tatooine by the name of Anakin Skywalker was this Chosen One.
Though Anakin seemed to have lost his way in the third movie of the then six-part saga (turning into a Sith Lord would do that, all right), he eventually redeemed himself at the end of Return Of The Jedi, becoming once again Anakin and killing The Emperor, ridding the galaxy of evil before dying.
Turns out, Anakin Skywalker was the Chosen One after all and, after a couple of decades on hiatus from his destiny, he eventually fulfilled the prophecy, bringing balance to the Force and ridding the galaxy of the Sith.
Until, of course, The Force Awakens. While Supreme Leader Snoke and Kylo Ren weren't technically Sith (the latter belonging to the Knights of Ren, an organisation whose purpose still hasn't really been explained), it was clear from the start of Episode VII that the Force didn't seem to be in "balance", after all. Luke's Jedi Order had disbanded, and an Empire-like organisation quickly swept in to re-take control of the galaxy.
This tarnishing of Anakin's legacy and the prophecy took another stride forward when The Rise Of Skywalker revealed that Emperor Palpatine had orchestrated the rise of the First Order, and had been pulling strings for years. So if Palpatine was alive, does that mean that ... Anakin didn't bring balance to the Force?
Disney tried to resolve this by having an Anakin Skywalker Force Ghost tell Rey to "bring balance to the Force, as I did", but come on - if this "balance" only lasts for a few years, is it really balance at all? This begs the question: who exactly was the Chosen One?
