First off, you're quoting @Slicer87 above, not me. But I'll jump in here to contest this notion that Kylo has "never been seriously challenged". He's meant to me "Master of the Knights of Ren"; and therefore a leader of bad men. Snoke even says to him: "Even you have never faced such a test." The clear implication being that he's been through some stuff to get where he is. The film effectively wants it both ways; as @Ingram_I pointed out in a particularly eloquent dissection. When Kylo needs to be tough and threatening and awesomely menacing, he's tough and threatening and awesomely menacing. When he needs to be an awkward wreck and bleeding wuss, he's an awkward wreck and bleeding wuss. It's certainly a different depiction for a Star Wars villain. I don't know if it's "bad" per se; but perhaps it's a bit too angst-ridden a portrayal for it to be entirely believable against the basic world parameters presented. Why does that duel image remind me of this chat? But anyway... I think you've made an analogy there that's both crooked and callow. ROTJ is Luke's third film and the throne room sequence is Luke and Vader's second confrontation. Luke obviously grows in power and ability across the films; even constructing his own lightsaber, as Vader identifies, to symbolize his own command of his previously latent and undeveloped abilities. Moreover, he's finally colour- and hand-matched to Vader in "Jedi" to starkly emphasize his similitude with his father. That's part of what makes their second encounter so visually striking and intense. Lucas controls his colours and his character arcs very well across the different (yet archly resonant) episodes. It's part of the joy of watching and revisiting these films. In TFA, by contrast, they did the storytelling equivalent of smearing vaseline on the lens to "fudge" things, making it easier (at the risk of hopelessly mixing metaphors) for queen to check king. Rey suddenly has a similar power-level to Luke, despite her mustard clothing, blatant lack of any recent training, and unfamiliarity with both a lightsaber and Kylo as an opponent. She doesn't even go into the fight in a particularly cool-headed way; yet still wins. Arguably, this alone is an anti-SW theme. The Emperor certainly works Luke into a state, but Young Skywalker exudes greater control and dexterity, befitting his enhanced abilities and cooler mindset since prematurely battling Vader on Cloud City. Also, you cite Vader's cybernetic strength, but this is a bit of a red herring when you consider who or what Vader is now up against in their second duel. Yes, he gave Luke a tough time on Cloud City, and he easily disposes of those "red shirt" rebels in "Rogue One" (if we're counting the Gareth Edwards film), but Luke is meant to be much tougher and meaner second time around. Vader can still menace Luke, but Luke is more apt to stand his ground and give back whatever Vader "throws" at him. The odds have evened up. Cybernetic strength, next to a well-trained Jedi warrior, isn't necessarily "all that". For instance, in ROTS, Grievous should rightly cream Obi-Wan in an instant; yet Obi-Wan is able to stand his ground and ultimately beat his robotic nemesis because he is supremely adept with the Force, and a seasoned combatant, in a way that Grievous isn't. It's the Force and being good with it that makes all the difference in Star Wars. But Rey is handed a big load of Force power on a silver platter (or *in* a silver lightsaber) and she doesn't really have to do anything to "earn" it. Even Anakin in TPM isn't ready to go swinging a lightsaber and cut Maul's head off. Controlled use of the Force against other Force-endowed sophisticates is meant to take time, hard work, patience, and experience to acquire. But Rey is "good to go" from her very first (and rather fretful) engagement. That's new.
