Droids
Why in gods name does han, leia and luke bring r2 and c3po to endor. In star wars they're unintentionally along for the ride and they serve a purpose. In empire, once again they're possessions that are packed up when escaping hoth. Kershner finds some pretty good ways to make them accessible to us and humanize them. He makes them useful but not in a cheap way. But in Jedi, they're just there, doing stupid things and the plot seems as if it was written to accomodate them.

Vader Doesn't Kill Anyone
So at this point in 1983, vader is really popular. Lucas realizing this, has to make him a good guy because everyone who is popular must be a babyface. It's almost like professional wrestling. After two movies of being an awful, murderous henchman, he now is transformed into some sort of tragedy and the emperor takes his place as the purely evil character. Why cant they both just be two really evil dudes? To make his redemption more believable Lucas doesn't have him kill or hurt anyone (other than the emperor) You just know watching the opening scene that moff jerjerkjdlsdfjlk is hurting for a choking. I wasn't really surprised to find out that a scene of vader choking moff jerjerklsdj; was cut from the movie. At least they delayed introducing him as the chosen one and allowing the trilogy to end on a somewhat respectable note.
