1) Rey is on a “heroine’s journey”, not a “hero’s journey”
2) As a pivotal part of this journey, Rey’s relationship with Ben Solo is “THE story of this sequel trilogy”, not a minor side plot to give her something else to do. (x)
3) Ben Solo is not a Villain™, he’s “a damaged anti-hero trying to prove himself a villain while longing for a connection to anything else…” So him being a shitty “main villain” is the point, as well as a positive thing. (x)
4) The sequel trilogy is immensely thematically connected to and inspired by the prequel trilogy, much more so than to the original, particularly in terms of Ben’s arc being an inversion of Anakin’s. (x, x)
5) “You can’t have a monster turning into a monster. That’s not a story.” –G. Lucas
^^ Quoting my own tags just to reiterate a bit that a major reason so much of the ST discourse is such a confused and confounding mess is bc Ben is so misunderstood and misinterpreted as a character. And he’s like, the linchpin character of the whole story. So if you don’t get him and the point of his place in the saga, then you don’t get the trilogy. He’s the key, but he’s also a lock, himself. So if you unlock Ben Solo, you unlock the whole entire narrative point of the sequel trilogy.
