R2-D2 mind-controlled the Death Star, wanting to destroy it more awesomelyThis would explain why Luke, who was a great pilot, was on the strike team instead of piloting an X-wing. R2-D2 begged him not to, not wanting to destroy his own project in such a lame way as torpedoes, and probably intending to self-destruct it in an awesome way. Luke agreed, but the Rebels still went ahead with their own (generic) plan.
The ending celebration montage takes place over several yearsAs someone pointed out on the "Just Bugs Me"-page, there's no way Coruscant - The Imperial Capital - would be in open celebration, only hours after the destruction of the Death Star and the death of the Emperor. Riots, stormtroopers everywhere, etc, seems more likely. The solution? The different scenes in the montage doesn't take place during the same time period. The shots of Luke and the others on the moon of Endor are obviously set only hours after the destruction of the Death Star, but the celebration on Coruscant could be months, or even years into the future
"Last of the Jedi will you be" is Yoda-speak for "You will be of the last Jedi"So, more Jedi do exist, but there are so few of them. This might help reconcile all the Jedi that survived without making Yoda either a liar or misinformed.
Ewoks are eaters of their defeated enemies.The Ewoks were completely ready to roast up Luke, Han, and Chewbacca for feast to honor their new god. While they get out of this unscathed, at the end there are quite a few Imperial helmets being used as drums, which makes you wonder what's the main course in the feast to celebrate their defeat of the Empire.
Palpatine threw the final battle.If you watch the battle among Luke, Vader, and Palpatine in the second half of the movie, you come to realize that Luke would have turned to the Dark Side instantly if Palpatine had just shut his mouth. This could have been Obfuscating Stupidity and the Villain Ball that he was carrying for the entire movie, or it could be that he had had enough of the Dark Side and wanted to die. (Then again, given how he spends the entire EU trying to come back, it was probably just the Villain Ball.)
The Sarlacc is a larval space slug.Back in The Empire Strikes Back, we saw a gigantic worm-like creature which tried to eat things and had a breathable atmosphere inside it, in an asteroid field that looked kind of like the results of the destruction of Alderaan (so it might originally have been on a planet). In Return of the Jedi, we see a smaller worm-like creature that tries to eat things; it was on a planet with a breathable atmosphere, no vegetable life, and a lot of Dune references. In Dune, the sandworms provided the atmosphere of Arrakis, and the atmosphere of Tatooine has to come from somewhere. Also consider that the Galaxy Far, Far Away is home to a very large number of very nasty organizations, all of which are eager to inflict the most horrible deaths they can on their enemies, but only one of them, and evidently not one that's exactly on the cutting edge of things like scientific knowledge and military equipment, uses the Sarlacc for executions. Thus, the Sarlacc is a larval form of a space slug, and space slugs are terraformers originally created by the Rakata or one of the other species of Precursors that the Galaxy Far, Far Away is positively swimming in. Like a space slug, it eats anything that gets close, but it digests things over a normal, less-than-a-thousand-years timeframe — it needs the biological molecules. (It can probably also handle metals and use those for structural purposes as well; it must get its energy from an internal cold-fusion reactor or thereabouts, as neither the Sarlacc nor the space slug had a diet that would provide enough energy for its extreme activity level.) Ask any xenobiologist, and he can tell you as much — and can probably give you a DNA sample and tell you where other creatures of the species are located, how long they take to mature, how long it takes a mature one to transform a desert wasteland into a comfortably habitable planet, and whether they die after the end of their Roaring Rampage of Terraforming or whether you have to kill them. Jabba, of course, was too clever for the xenobiologists and asked the local Jawas instead, explaining why he's the only person in the galaxy who throws people into the Sarlacc as opposed to inflicting some other, more conventional, form of horrible death. Its form as depicted in the original version of Return of the Jedi is a very "newly-hatched" stage, where the characteristic space-slug mouth is still developing; its form as of the Special Edition (which was what Lucas wanted to do to begin with, although he didn't have the budget) is a later-stage juvenile space slug.
The Ewoks are the most bad-ass race in the Galaxy.They're willing to take on enemies with far more advanced weapons, like AT-S Ts and blasters, which takes guts. They are able to create huge suspended villages and set up effective traps in a short amount of time, which shows good planning and discipline. They aren't afraid to use unfamiliar technology, which makes them adaptable. And finally, there appears to be thousands of the little buggers, which could indicate rapid breeding. If they ever get off planet, they might start their own empire.
The Sarlacc is actually an Eldritch Abomination that serves as a portal to Hell, and the people telling otherwise were making the whole thing upHence why the people who falls in there will be in great pain, for a thousand years, if not eternity. On the other hand, it's not just a thousand-years digestion, it could be worse....
The Ewoks are the Furlings of Stargate fame.Think about it. The Ewoks created huge villages suspended from the trees, and fended off a troop of Imperial forces, armed with slingshots and rocks. A species with that much intelligence and skill could have easily been one of the four races if they had a stargate.
Simply Striking Down Palpatine Wouldn't Have Turned Luke to the Dark Side......and Palpatine is fully aware of that. Killing Palpatine would've effectively been something heroic, it would have saved the lives of millions, so it was only justified. However, Palpatine is a Magnificent Bastard, after all. Once he directly points out that he's defenceless (except for the electricity Luke probably doesn't know about) then it stops being outright heroric. Palpatine then messes with Luke's head. If Luke did strike Palpatine down, he would've gone to the Dark Side because he believed he'd fallen to the Dark Side, due to misplaced guilt and all that. Imagine if Luke wasn't so lawful and was instead an Anti-Hero, and simply went "Shut Up, Hannibal!" and Force-pulled his lightsaber and chopped him down then and there. Would that really have dragged him to the dark side on its own?
Anakin brought balance to the force by killing PalpatineThe Sith is not what was causing the imbalance, it was Palpatine. So, with the death of Palpatine, the Force was brought into balance.
Palpatine lied about being unarmedIn Revenge of the Sith, when Mace and several other Jedi came up to his office to arrest him, he had his lightsaber pop out of some kind of springloaded sleave holster and went on the attack. It would hardly be a stretch of the imagination for him to still use that lightsaber and its rig, since he would be able to defend himself if a would-be assassin defeated his elite bodyguards (Vader can't be at his side all the time, you know). Why he didn't whip it out and use it is the real puzzler though...
Vader threw the fight with Luke because he couldn't bring himself to kill his own sonThe only time you see Vader really try to kill Luke is in A New Hope during the Trench Run, and he doesn't even know who Luke is at that point. When the Emperor tells him that "I have no doubt this boy is the offspring of Anakin Skywalker." Vader's first thought is how to turn Luke, so that they could overthrow the Emperor and end the war, ruling the galaxy as Father and Son. Him fighting Luke at Cloud City was a test, to see what his son's strengths were, and to try and sway him to Vader's side. Cutting off Luke's hand was an accident, which is why Vader stops attacking him at this point in the duel and instead reveals the truth, hoping to finally sway Luke to join him in overthrowing the Emperor. Come Return of the Jedi, Vader is reluctant to bring Luke to the Emperor, but does so mostly out of hope that Luke will join him. His comment "It is pointless to resist" is him telling Luke to give in to his hatred of the Emperor, so that they can kill him and become the new rulers. When Luke makes a move to kill Palpatine, Vader steps in to stop Luke from turning to the Dark Side because he knows that Luke, having been swayed by Palpatine, will merely replace Palpaine rather than join with Vader. Notice that never once does Vader even come close to killing Luke, and Luke even manages to get the upper hand a few times (Force Kicking Vader down the stairs). When Luke hides in the shadows, Vader once again tries to talk him into joining him in striking down Palpatine ("Give yourself to the dark side. It is the only way you can save your friends.") His talk of turning Leia to the Dark Side is a furtherance of his goal of having the Skywalker family united and ruling a peaceful galaxy. When Luke attacks him this time, he cannot fight back without hurting/killing Luke, which leads to him losing a hand and almost dying at Luke's hand. If you look closely when Vader is lying on the catwalk, you can see him moving his hand as if to say, "Calm down, control yourself," to Luke, who is still wanting to kill him at that moment. He is trying to calm his Luke because killing Vader would leave Luke to be trained by Palpatine i.e. not part of the Vader Master Plan. In the end, he turns back to the Light Side and kills Palpatine once he realizes that this is a replay of the moment that he turned to the Dark Side: a Jedi is about to be killed by Palpatine right in front of him, and he has to make a decision who he will side with. This time, he chooses to reject Palpatine in order to save his son, and dies for it.
Ben and Yoda lied to Luke specifically so he could kill Vader.While Yoda tells Luke that they lied because they didn't think he could stand the truth, he was still lying. When he and Ben told Luke that Anakin was utterly lost to the Dark Side, they were lying. They knew that Vader might still have some spark of good left in him, but they didn't want that spark revived. Why? Because they didn't want Anakin redeemed. After years of brooding over their failure and mourning their dead friends, Ben and Yoda wanted Vader punished for his crimes. They wanted him dead and rotting in Sith Hell, not redeemed by the Light Side and getting into Jedi Heaven. So, they lied to Luke so that he'd feel righteous anger (though not Dark Side anger) towards his father's supposed murderer, then go off and cut the armored buzzard down without a second thought. That's also why they didn't want him to try to save his friends: more programming for their cause and more reasons to hate Vader's guts. Fortunately for everyone, Luke saw the truth and took the right path, resulting in Anakin's redemption, Palpatine's death and freedom for the galaxy.
The second Death Star was built faster than the first one because of spare parts.The original Death Star was the first, so most of its elements had to be specifically created. While doing that, the Empire decided to produce spare parts as well, just in case. When the Death Star was destroyed, the Empire built the shield generator on Endor (which took longer than actually building the Death Star II) and then built the second Death Star using spare parts.
The Ewoks will eventually take over the galaxy.The little Badass Adorable teddies can wipe out an entire army of apparently highly trained super soldiers, who have high tech weapons. The Ewoks used nothing but primitive sticks and stones. Surely the dead stormtroopers must have left much of their technology behind after their defeat. Just imagine once the Ewoks get the hang of using that technology.
Leia's memories of her mother are visions from the Force.In The Empire Strikes Back, Yoda told Luke that, through the Force, Jedi could see visions of the past, as well as the future. A young Leia, being strong in the Force, saw visions of Padme, her birth mother. However, Leia, not knowing about her true heritage, didn't realize just what she was really seeing. So, she interpreted them as being actual, if fragmented, memories of her mother. It's possible Luke had similar visions, but he responded by just putting them out of his mind, since he apparently knew next to nothing about his real mother and had no true frame of reference.
Darth Sidious saw Vader's betrayal coming yet not as soon as it did.Darth Sidious's reaction when being picked up by Darth Vader was like he was expecting Vader's betrayal yet was not done killing Luke yet. He most likely thought that he had enough time to kill Luke and truely turn Vader to The Dark Side. He saw Vader's hesitance to kill Luke during his Holo message and realized Vader still had good in him so when Luke refused to turn to The Dark Side he decided to finish Vader's turn to darkness by killing Luke and inciting Vader to vengance. What he did not expect was that he took too much time in killing Luke that Anakin would spring into action to stop him during the killing not after. Darth Sidious's fall wasn't an  it was a  moment which as all such moments do took too long and ended ruining his plan.
Yoda didn't fancy Luke's chances much.His training was clearly incomplete. Yet Luke will, according to Yoda, become a Jedi if he confronts Vader. Essentially what Yoda was implying was basically "if you manage to confront Vader and survive the experience/aren't turned to the Dark Side, you might just be good enough to be a Jedi after all." Except he doesn't quite put it like that, lest Luke be discouraged.
Luke and Leia being siblings was a last-minute addition by Lucas.Though Lucas may claim that he planned it all out, that would make [[Twincest the kiss between the two]] and the semi-flirtation really squicky(or hot), making us question Lucas' tastes. Originally, Lucas wanted a Love Triangle between Luke, Han and Leia. However he had to resolve it with Han and Leia pairing up, considering how popular the pairing was. And as we all know, Lucas is known for two things: Shocking family revelations and piss-poor romance stories. Leia being Luke's sister combined them both. Lucas thought we'd just forget the original Love Triangle angle, but even [[Rule34 before the internet]] people are going to jump to conclusions.
