Star Wars: return of the Jedi needs a re-boot. There are so many implausibilities that it's down right distracting. Let's start with Luke confronting Jabba. First of all , a Jedi NEVER willing separates himself from his light saber. Moreover, if he didn't want it to be seen, he could have hid it on his person. If you noticed, he was never searched by Jabba's goons. Also, if he wanted to , he could have fought his way through or snuck in at night, got Han and left using the force to disguise his presence. He could have also brought with him a squad of rebel soldiers who would feel obligated to help Luke after all he's done for them previously. So there were better ways to rescue Han that made cinematic sense.
Secondly on Degobah Yoda tells Luke that only a fully trained Jedi ,with the power of the force as his alley can defeat Vader and his emperor, yet he tells Luke in 'Jedi' ,"no more training do you require. Know now all that you need." Luke says: "So I am Jedi", but Yoda corrects him saying that only after confronting Vader will you become a Jedi. WHAT? He's says in 'Empire ' you can't defeat the two if your NOT a fully trained Jedi, and then in 'Jedi' he says confront Vader then you will be a Jedi. Do you see the contradiction?
Third the Emperor tells Luke that he has a legion of his BEST troops on Endor. A legion is between 3000 and 6000 men. And he said his best! troops. If any have watched the 'Clone Wars' animated series or played 'Battle Front' you know these elite clone troopers are very professional and lethal, so I ask you:
HOW ARE LITTLE TEDDY BEARS WITH STONE AGE WEAPONS GOING TO EVEN REMOTELY KILL EVEN ONE TROOPER! Now the storm troopers have THE BEST weapons the Empire can supply especially because of the seriousness of the mission and the gravity of protecting the new Death Star.
The Rebels have maybe 20 guys plus Han and Chewy(Luke was rendered useless in their defense because of his surrender), so they weren't a real threat. Plus the Empire had 'Chicken Walkers ' too.
Moreover, the time span between Han and the rest being captured and C-3p0 taunting the storm troopers to chase him in the woods ,which is something a disciplined unit would NEVER DO, that is to abandon their post to chase a harmless, unarmed droid into the woods, is about 2-3 hours at best. Now how are stone age teddy bears going to cut down about 20-30 VERY LARGE trees with stone tools. It would probably take 20-30 of them just to cut down one, and take at least 2 hours. So here they have all these very large logs cut to size behind a barricade on a hill(somehow they moved them through the forest) to be released when a Walker passes. They somehow also, in just a couple of hours mind you, hoist two giant logs about 40 yards into the tree canopy which wight about 2-3 ton each easy . It is UTTERLY impossible!
Now the storm troopers have armor, yet it provides zero protection against...you guessed it...rocks! And rocks thrown by teddy bears. C'mom man!
Fourthly, the whole Leia as Luke's sister thing is bogus. Lucas never intended her to be that 'other person' Yoda mentioned to Obi-wan on Degobah saying, "there is another" in 'Empire'. If he did, he wouldn't have had that kissing scene with Luke and she on Hoth. This was a lazy plot devise. Whoever Lucas had in mind to be the 'other' could had helped Luke in some way and be a foundation for the next movie. But NOOOOOO, we get some creepy incest scenario.
Finally, Anakin's ghost. Wrong! As Darth Vader , he,and I quote Obi-wan on Tattoine: "He(Vader) helped the Empire hunt down and destroy the Jedi...". He was responsible for countless deaths! How can he , by killing the Emperor redeem himself and thus be found worthy to stand next to Obi-wan and Yoda. Damn Lucas, Vader killed Obi-wan! Just Obi-wan and Yoda's Ghost should have visited Luke during the celebration.
If Lucas insists on changing the classics, then re-boot 'The Return of the Jedi'.
Thank you for your time.
