Welcome :)
I hate Star Wars but I can't help myself from talking about it. It is my Sisyphean torture. I appreciate that it's been civil which seems like a rarity within Stahr Wahrs. Of course I do agree that Rey's character isn't as well defined as the OT trio, but she's at least above prequel tier. And I get it, I get the issues many have, there's a lot of greater issues with the sequels (like a lack of a defined plan), but episode 8 was like a reminder why I thought Star Wars was neato skeeto. That said, once more around the horn.
I'm not sure distance matters quite as much. Rey was in fight or flight mode and the lightsaber 'called to her' so the script said earlier. The Force doesn't mean someone needs training to tap into it - Broom Kid is proof enough of that - but given that Rey is 'embracing her destiny' with that moment, it's equal parts dramatic coda and character defining. Luke was under duress and struggled and Rey struggled as well - against Kylo who was also trying to get the saber.I chalk that scene down to cinematic convenience and the aforementioned wow effect that isn't really meant to have much logical depth behind it. My main issue is that based on what I've seen of star wars over the years, distance does play a part. It is good to bring up the 'fight or flight' line of logic as I can factor it in as a rather potent modifier for the scene, but I think the distance was a bit excessive for someone who simply never went in that direction in the first place. But, again, it is not something I can argue any further for, as I simply don't have enough familiarity with the scene nor enough ideas of how it fits into everything else for me to be confident in trying to press my case home.
I don't think there's much of an issue with a lack of 'practice' given that all we ever see Luke do on screen is deflect bolts, move his saber, and do some gymnastics with rocks. Episode 6 has the implication that he went back for more training but the same isn't exactly said for episode 5. Luke's training was never really the vital point so much as it was expansion of the Force - that even someone like Yoda could do extraordinary things. Luke in the movies isn't exactly the most competent of Jedi even with his masters being two of the best.
I clicked it, yes, but I didn't watch it. I intend to if only because it's probably a perspective that I can't exactly have.
You'll have to ask Kasdan and Abrams for that. I don't disagree, which is why Snoke dying is the best thing they could've done.
The Jedi are constant failures no matter what point of history it is, so Luke does carry on the tradition of failing and learning from it only when an opportune moment arises to do so. It's what makes his ultimate fate in TLJ so satisfying because he learns his greatest lesson and does the single coolest thing a Jedi has done on screen. Luke was awesome.
I think a major problem is because The Force is so ill defined that it creates situations where expanding it just creates more problems. Star Wars works best when it's not taken super seriously, but that doesn't mean serious and good stories can't be told within universe.
The circumstances were different for both cases. Luke was disoriented and had been hung upside down for a considerable amount of time - and in both cases Luke and Rey close their eyes to tap into the Force to accomplish their goals.
What training was he given by Kenobi, exactly? He put on a helmet and deflected a few bolts from a game droid. He didn't even have any actual formal training until Empire and yet at the end of A New Hope he blatantly uses the Force to blow up the Death Star - just because Kenobi told him to "Use the Force". Which is almost exactly how Rey manages to win the fight, just without Lupita Nyongo whispering it in her ear. Nothing Rey did is out of the ordinary given what we see of her experiences in the movie.
He's not cunning or strategic, which is why Hux was about to kill him in that brief window. What he is is unhinged and angry and he has a rather large army at his disposal. The First Order has numbers now that there's no government and the Resistance is scrounging for numbers in the Outer Rim. The fact that he's not a strategist, but an emotional figure is the entire point. Here's someone who has an absolute authority over a military and a vendetta against those who slighted him. The threat comes from the fact that he's willing to use the army for his own selfish goals and it's not like there's a governmental or military body set to oppose him.
Snoke was dumb and killing him to make the actual interesting character the antagonist was the best possible move.
You're right. He's also noted as being rash and prone to poor decision making, overconfidence and poor planning, and ultimately heroic when the need calls for it. He carried on the traditions of his teachers pretty flawlessly too.
Expanding on the concepts is what lead to the only decent bit of Star Wars there is, which was an entire narrative about how the Force is stupid and makes no sense.
