I can definitely agree that this is the worst of the original three. This mainly stems from the fact that the story itself is lame. The cardinal sin is that Han turns into a giant wimp! This is the guy who continually conned Jabba, coolly fried Greedo, destroyed Star's End, faced down Boba Fett (why, oh why did we have to have a blind Han take out Boba? We know he's good but we want a real fight between them!), and stood up to Vader. ROTJ makes him mushy! Arrrgh!
Palpatine is the best part of the film, with his goading of Luke adding the only real spark in the entire film. Then the "climactic" battle between father and son is all too brief and marred by waaaay too much cross cutting between the Battle of Endor and Lando in the Falcon. (What? Why doesn't Han pilot in the most famed space battle ever? Oh, beacuase in this movie he is a lame duck!)
I have no problem with the ewoks (can't believe I said that.). The idea of rocks, spear, and logs triumphing over the Empire's best troops seems a bit absurd-but it barely works. (Palpy needs some better instructors over at the academy...)
ROTJ should have been subtitled 3P0's Revenge!
The film most suffers from inadequate scipt and story, but moreover from the lack of a good director's control. I have nothing against richard Marquand, but he seems to have been swept up in the vast SW machine. It is said that Steven Spielberg was originally to direct ROTJ. This would have fit perfectly, ROTJ could have been a great film with this fact in mind and if someone had actually decided to write an effective screenplay!!!
I actually agree with the 97 ending music being superior. Upon finally seeing an acceptable original version with the famed "yub nub", I was like: that's it? That's how SW originally ended? Oooookay? The new music adds a sense of finality and respite from danger. It fits the film better than "yub nub" which seems goofy and more out of place than "Jedi Rocks". (Why the hell is that called Jedi Rocks anyway? I never knew a Jedi that rocked. Mace Windu perhaps did so.) This may be just me, as I have read previous posts praising "yub nub".
The "plan" to rescue Han is absolutely retarded and takes up way too much time. One by one our heroes go in to rescue Han and they all fail! Oh yeah, Luke's plan was that they all get captured and fight their way out. Great plan. Lando probably suggested this all for his badass reveal close up-"Oh yeah...it's really me-Lando Calrissian and I am still the administrator of this facility! What now!"
All in all, ROTJ is an acceptable film. IV and V are so beyond VI that it makes VI's mistakes and problems much more noticeable. Otherwise, ROTJ would be much less scrutinized.
Hey, at least it's better than the prequels.
