Anyway, yes, George Lucas definitely flirted with the dark side (i.e. the leftist dogma his pals were pushing) in film school and ultimately tumbled to it a long time ago. Like many a leftist who substitutes "big corporations" for "big government" and "fascist" for "commie" as his favorite objects of blame for being the source of all things evil, the close relation between Communism's international socialism and Nazism's national socialism is typically lost on him, as is the irony of bashing big corporations while selling his company and its franchise off to Disney's gargantuan corporate conglomerate. The incestuous relationship between corporations and governments in actual fascism, of course, leaves who has ownership of whom far more ambiguous; the Nazis' main reason for purging Ernst Roehm and his loathsome S.A. was that they were determined to put a stop to his rather Stalin-esque plan to nationalize their corporate bedfellows, but only because they considered themselves to be the real controllers of those corporations and weren't about to hand control of their "turf" over to anyone else.
In any case, The Last Jedi actually did leave plenty of questions to be answered, though again I wonder whether J.J. Abrams can work up the proper resolve to answer them:
1. So who was Snoke anyway, and how did he corrupt Ben Solo into Kylo Ren? (Industry rumors indicate Andy Serkis is still on call to reprise his role as Snoke in episode IX, if only in a flashback, so we might actually get an answer to this one.)
2. Now that Kylo Ren has actually done what Darth Vader always planned on doing (killing his master and taking control of his empire), how effectively will he actually rule? How many insubordinate underlings (such as General Hux, for one) is he going to have to Force choke to keep the rest of the First Order in line?
3. Will hyperspace missiles based on replicating Holdo's final heroic sacrifice become the galaxy's new super-weapons, sparking an arms race that renders Death Stars and everything else like them (*cough* Starkiller Base *cough*) obsolete?
4. Are any of the main characters' potential romances going to come to fruition? (If the "romance" in question proves to be between Finn & Poe or Rey & Rose, however, that's where I abandon the franchise forever, just as I abandoned Marvel Comics back in the early aughts for the very same reason.)
5. Are those last two dozen or so survivors really all that's left of the Resistance, or were their Outer Rim allies actually just too busy with the First Order in their own corners of the galaxy to answer their call for help?
6. Where's Lando Calrissian?
7. What have those Knights of Ren (heavily implied to be Luke's other apprentices Kylo Ren corrupted) been doing in the last two movies, and what will they be doing in this one?
8. What are Rey and Ren going to do about their involuntary Force bond with each other (still present even now that Snoke's gone), from which (incidentally) the novelizations indicate she's been receiving so much of that raw power and rapid training that has her detractors calling her a Mary Sue?
9. Now that Yoda has established Force ghosts can do things like calling up lightning storms from the afterlife, what will Force Ghost Luke Skywalker be doing in this next movie? (Like Alec Guinness before him, Mark Hamill will almost certainly be returning for at least one more paycheck.)
10. Of course, the biggest question of all The Last Jedi left unanswered: what becomes of Leia now that Carrie Fisher is gone and LucasFilm has sworn not to recreate her digitally?
Hmm, yeah, I’m not so sure nihilism and Nietzschean philosophy would have been even remotely conservative (Hideo Kojima and the Wachowskis were definitely adherents to Nietzschean philosophy, the former even quoting Nietzsche’s “there are no facts, there are only interpretations” dictum in a certain infamous twist ending to MGSV, and the latter makes clear in an interview that they had based their trilogy on the works of Nietzsche, as well as Theodor Adorno and Arthur Schopenhauer, and those guys definitely were not conservative or right-wing by any stretch). Though yeah, the left definitely has a tendency to call anyone they dislike Nazis, often failing to realize that the Nazis actually are on the same spectrum as the left. And eh, unless there’s a noticeable change in profits over a person’s appearance, I don’t really give a darn about physical appearances (besides, he’s a guy, I’m a guy, I wouldn’t find him attractive since I only focus on the opposite sex).
And yeah, Lucas definitely tried to push a lot of leftist thought, and certainly was a leftist himself. Ironically, though, regarding big government and big corporations bits, the Empire’s not even fascist if you really think about it: In the old EU at least, there was this group known as the Corporate Sector Authority that inhabited a region of space called the Corporate Sector, which was effectively a Corporatist fiefdom. Anyways, after the Empire was formed, the Empire managed to expand their territory by about 30,000 star systems, gave them more legroom in other words, and other than maybe a yearly tax, they don’t demand anything else from them, and if the Imperial Handbook is anything to go by, they actually deliberately avoid interfering with the CSA specifically to allow for transparent mercantilism due to having zero problem with corporate competition in itself, and implied that this was the reason for the booming economy. I simply can’t imagine even the Nazis doing that, let alone the Communists, since that comes closer to what Adam Smith advocated with free markets. Of course, then again, the EU generally tried to depict the CSA as being at least as bad as if not even worse than the Empire due to it being made up of Corporations (essentially the Trade Federation and/or Separatists from the prequel trilogy before there was a prequel trilogy) to the extent that the New Republic after being formed effectively boycotted the organization in the EU, and in fact, it debuted in a Han Solo story where he essentially stole money from it and we’re supposed to root for him. And on that note, I know you mentioned that deleted scene from A New Hope, but I didn’t see any indication in the Imperial Handbook that the Empire had any interest, long or short term, in nationalizing moisture farms (and believe me, considering the book made clear they nationalized some industries, and were willing to commit speciescide if such measures were necessary, plus taking control of the HoloNet, if they actually were planning to nationalize something like moisture farms in the old canon, they would have specifically mentioned it in that book, and that book in-universe was first published around the time of A New Hope based on some of the comments.). And far as Rohm, heck, Rohm’s plan wasn’t even Stalinistic (in fact, ironically, Hitler himself came closer to acting like Stalin during that time), Rohm’s plan if anything was closer to being outright Trotskyite (since he desired permanent, continuous revolution, which is a key tenant of Trotsky that Stalin ignored in favor of Socialism in one country). But otherwise, I agree with you fully on that bit about why Rohm and the SA were wiped out (his homosexuality had very little to do with his death, especially when Hitler was fully aware long beforehand). Heck, forget the communist or fascist things Lucas argues for and misses the point on, in I think the 2005 Cannes Film Festival, he actually implies at one point that he based the Old Republic on, among other things, Robespierre’s French Republic and that it was at the very least better than either King Louis XVI’s France or Napoleon’s France. Now, I can understand why he might base it on the Weimar Republic (that was a broken system that ultimately made Nazi Germany or even Soviet Germany inevitable thanks to the stupidity of forcing Germany to give up its monarchy at the behest of that idiot Woodrow Wilson), or even the Roman Republic (while not quite as bad as the Weimar Republic, the Roman Republic nonetheless showed some elements of corruption as well), but Robespierre’s French Republic made the Old Republic look even WORSE than the films implied since it would result in the implication that the Republic just had mobs slaughtering people left and right for a sheer kick, many of which were exceptionally brutal. I don’t think you can get any more proof of his being a leftist than that (since the left tends to worship the French Revolution to some degree, some only going as far as to support the generalities, some actually worshipping the more depraved elements like the Reign of Terror or the September Massacres).
Regarding those questions you brought up.
1. If they kept him alive, they would have actually answered that question in the next movie. Sadly, they killed him off prematurely, so it’s unlikely they’ll do so unless they manage to have him pull an Emperor Mateus from Final Fantasy II and, say, come back from Hell in a bestial form to take over both sides of the plane of existence.
2. Considering how the ending was shown, I’m not even sure the First Order’s even going to have much respect for Kylo Ren at all.
3. Yeah, I’m doubtful they’re going to cover that in the new movie. Besides, even if they were to, that was technically an extension of the trick Han Solo used to get on Starkiller Base (and quite frankly, in both instances that was a stupid plot point. I mean, really, if it were THAT simple to hyperspace beyond a planetary shield, or deflector shield of any sort, they wouldn’t have even NEEDED to blow up the shield generator on Endor in ROTJ, they’d just hype in and blow it up, save them a whole lot of trouble.).
4. Maybe, maybe not. At the very least, Finn and Rose’s romance is pretty much confirmed.
5. Probably the only other person I can think of who might be of some help is Maz (who is dealing with a trade dispute that was bad enough that she’s in a firefight as a result), and considering none arrived to make the call, I’m pretty sure that’s all they’ve got left.
6. We were actually going to see him in The Last Jedi. But unfortunately, they decided to cut his scene out and replaced him (he was apparently going to be Rose and Finn’s contact at Canto Bight, the one whom they never got a chance to meet because the police arrested them for illegal parking before they could do so).
7. Okay, now THAT one might actually be addressed in Episode IX. Though then again, they didn’t show them at all in Episode VIII, which would have been a perfect time to show them off.
8. It probably will still be there.
9. Maybe we’ll find out, maybe not (let’s not forget that Mark Hamill DID give a strongly worded complaint about how Luke was handled in the film, so that might affect his chances of being hired again especially if Disney management right now is intolerant of any deviance from their lockstep SJW ideology right now).
10. That’s easy, they’re probably going to do to her what they did to Tank in The Matrix Reloaded (ie, kill her off offscreen). I don’t need to know the plot for Episode IX to know that.
