I saw ROTJ as a 9 yo and LOVED it! I recall the huge anticipation I had to see the space battle(I'm an x-wing fanatic, its the greatest fighter...EVER!) and the revealing of Anakin skywalker. Several of my friends told me in advance that the movie was awesome. I still love the film, love the unfinished look of DSII and love Luke's journey to jedi knighthood. The only change I would make nowadays is having Leia abducted by bounty hunters during hans rescue on tatooine. the bounty hunters deliver her to Vader and the emperor, for they already know that leia is a potential force user, Vader's daughter and is going to turn her to the darkside in the hopes that Luke will follow as well. And the rebels to stage a final assault on an imperial city headquarters on Endor rather than another DS assault. The Emperor,Vader take Leia to an ancient Sith temple in the heart of imperial city. in a nutshell the battle would go as:
The rebel fleet en masse, attacks the star destroyer blockade guarding Endor to provide a window for han,luke, chewy and multiple rebel ground assault teams to invade Endor and initiate a ground assault on imperial city. The rebels are armed with lots of cool ground assault vehicles, cannons etc. Han heads the main ground force with Luke taking a small platoon of soldiers in the 2nd wave and infiltrates imperial city to the sith temple. Inside the dark sith temple, luke tries to persuade Vader to go back to the good side and release his daughter, so they can be a family. Vader fights instead, still loses his hand and yields. Luke then refuses the Emperor's offer and demands the release of leia. The emporor attacks luke with lightning, which luke initially blocks. Along with lightning, the emporor force attacks with multiple projectiles. Luke, being pummeled to death asks for his father's help. Leia screams for her father's help, in which the Emporor turns around and force chokes her. Anakin reaches up and attempts a force choke on the emporor, who shifts his lightning attack on anakin. Luke, battered and bloody uses that window of opportunity to lunge forward and impail the emperor, then decapitate him. Luke and leia remove Vader's mask to see their father, who dies shortly, burn down the sith temple and leave the destroyed imperial city. During the celebration, Luke announces a new jedi academy and will seek out desciples throughout the galaxy
