The celebrations on Couruscant were explained away in the books as being temporary rebellions that were quickly pacified. As for the ones on Besbin Tattooine and Naboo they are relatively out of the way planets and could probably get away with it.
On the special editions when people fall into the sarlac they disappear a split second before they go into the mouth also did anyone notice ET's hand in Jabbas palace (when C3PO is being taken to the droid torture chamber).
The Executor hit the Death Star because it was pulled down by the Death Star's gravity and the back up control rooms didn't have enough time to save it, after all it hit the death star 5 seconds after loosing the bridge that's not a lot of time.
The Ewoks defeating the storm troopers was ridiculous, makes you wish they'd gone with the idea of the Wookies home planet instead, that would be a credible battle and well worth seeing.
Lucas Film have tried to back away from the Ewoks winning and saying things like they just led the troopers into the forest and then when the shield generator was destroyed the troopers surrendered and that most of the legion was at the other entrance. But there is one scene where a Scout Trooper gets killed by one of the Ewoks pathetic wooden arrows, Scout Trooepr armour is bullet proof an arrow wouldn't even scratch it.
"By Andrew Kibelbek on Monday, December 21, 1998 - 5:28 pm:
When Han Solo is frozen in ESB, he has a rope binding his upper arms to his sides. He wears plain blue pants. When Leia unfreezes him and he falls out onto the floor, the bond is gone, and now his pants have racing stripes. "
Actually, I just watched 'Empire' last night, Han was indeed wearing the blue pants with yellow stripes along the seams. Also, as he was being lowered into the freezer, the short dudes were removing his hand binders, so they may have removed the one restricting his arms when the camera cut away.
I just want to say that I'm ruddy sick of Ewoks!
This has bothered me for a while....
The Emperor's temptation to Luke... he makes it sounds like that Luke has no choice but to embrace the Dark Side.
Is the Emperor implying that Luke has no free will?
Is the Emperor implying that Luke has no free will?
Palpy thinks that since the other choice is Luke being killed, Luke will choose life and service to the Sith.
Admiral Ackbar tells the fleet to jump to hyperspace on his mark.
Only problem is that Lando and the rest of the fleet jump immediately without waiting for the mark.
A couple more...
At the party on Endor, several X-Wing pilots are celebrating... in their flight gear. Didn't they have time to change?
If Anakin Force-ghosted, then how is there a body for Luke to burn on the pyre?
Luke asks Leia what she remembers of her real mother.
Leia says she has a few memories. Didn't Padme die in childbirth? How can Leia have ANY memories of her?
In the real world, that aspect of her birth had not yet been defined when the movie was made, but of course we are nitpickers and we don't deal in reality.
Midi-chlorians - not mentioned once in Luke's training!
Planets that "elect" fourteen year olds as Queen (democratically, of course)
Jabba's attitude toward Luke's warnings was very dismissive and casual for someone who was alive at the time of the Old Republic and was fully aware of just how dangerous a Jedi can be.
We are clearly shown that the speeder bike's speed is controlled by a foot pedal. The Ewok's legs are too short to reach that pedal, so how can the Ewok fly the speeder he stole?
The two scouts being chased by Luke and Leia should have separated, that way at least one of them could have escaped and given the alarm.
After injuring Leia at the bunker's door, why did the storm troopers try to capture the small rebel group instead of just finishing them off?
When the Falcon goes to light speed as the rebel fleet starts on its way, Lando's co pilot activates some control switches above him to his right. In all previous instances, light speed is activated by moving some levers on the console in front of the pilot.
Lando orders his group of fighters to split up and head back to the surface of the Death Star, hopefully taking some of the pursuing tie fighters with them. However, the group of rebels remaining on course for the power generator was clearly the greater threat and all the tie fighters should have stayed with them.
Luke's light saber should have made a much cleaner uniform cut through Vader's wrist instead of the mess of twisted dangling wires we are shown.
Luke stands remarkably close to Vader's funeral pyre as it burns. A fire of this size is HOT.
And speaking of fire, I don't think it's a good idea for the Ewoks to make bonfires on the wooden platforms of their village up in the trees, that's courting disaster.
Who are worse, Ewoks or Tribbles?
Ewoks. Tribbles are easy to deal with, just don't over feed them. And they make a pleasant cooing sound. 
Somehow its hard to buy the defeat of crack stormtroopers by teddy bears.
Jabba's attitude toward Luke's warnings was very dismissive and casual for someone who was alive at the time of the Old Republic and was fully aware of just how dangerous a Jedi can be.
Well, as Jabba put it in a deleted line addressed to Luke, he'd killed Jedi before, "back when killing your kind meant something".
Honestly, I feel like Harrison Ford had just ... stopped acting by this point? It's like those episodes of Doctor Who where you can tell Tom Baker has checked out.
The Emperor's plan would have worked if it weren't for the Ewoks.
Actually, the Emperor is a Sith, and a very skilled Sith. He should have foreseen the Ewoks potentially messing up his plan and have been prepared for it.
There's only a single Jedi at the end - Luke. Anyone watching One to Six in chrono might feel cheated by the title of this film as nearly ten thousand Jedi are implied to be killed in ROTS. It's hardly a comeback - from a Certain Point of View.
