Nah, unless you’re making a Trek riff, it is serious in that, we’ve Kylo doing all this stuff but I don’t see why he’s doing it.
I find that interesting as a standpoint, because it’s really the opposite. Kylo Ren is literally the only character in Star Wars who’s motivations are based on his personality and backstory rather than the needs of the plot.
For example: Why does Han choose to rescue Luke at the end of Star Wars? Why does he then return to being selfish in Empire, and go back to being Heroic in Jedi? Why does Leia move from being abrasive to courteous and back between Hope and Empire? you talk of Darth Vader wanting to bring order to the Galaxy, but why does he want this? Why did he want to supplant the Emperor and rule with Luke? You might have an answer to those initial questions, but ask why one or two more times and it’ll wind up being just because.
This is because Star Wars for the most part is going for epic sweep and scale rather than epic characters. Most of the characters are archetypes and as such fuelled by simple motivations. This isn’t a bad thing, it makes it easier to identify with them and understand, and it plays into the broad emotional arcs that are Star Wars’ bread and butter.
By comparison, Kylo Ren’s motivation is that he hates, and he’s frustrated and he’s angry. It stems from his encounter with Luke, yes, but it’s a traumatic moment that informs his character rather than defines his actions. His bad experience with Jedi training drove him to Snoke - and as we see Snoke treats him like shit, which is just going to make him hate everyone and everything even more. He wants to tear down the traditions of both the light side and the dark side because they both failed him. He lashes out at everything because he gets no emotional support. And then when he’s got a chance to get that support from Rey, he fucks it up by trying to pull the same line that Vader tied on Luke - only he killed the Emperor before making the offer. @Jason described him as a 4channer, and @Jim likened him to a school shooter, and they’re not terribly far from the mark, because the core of Kylo’s character is that unfettered frustration at a world you can’t understand or control. It’s fascinating as a character study and the most interesting thing that Star Wars has ever done.
