Balance To The Force
The references to the prequels don’t stop with the namecheck of Darth Sidious though, as there’s also a lot of discussion inĀ The Last JediĀ about how there needs to be balance to the Force.
For instance, it’s Snoke’s theory that an avatar for the light side of the Force would rise up to combat Kylo Ren’s darkness. He initially believed this to be Luke, but it turns out to be Rey. Likewise, Luke says the Force was in balance until Ben Solo turned to the dark side.
The idea of bringing balance to the Force was previously a major theme of the prequel movies. Anakin Skywalker was the prophecised Chosen One who was promised to be that balance. What the Jedi didn’t know is that he would be the darkness that balanced out their light.
Nowadays, the two sides are simply embodied by Rey and Ren. Though things might be swinging back in the light’s favour, as the film’s final moments saw a young boy on Canto Bight exhibiting Force powers.
