Spence you said a copuple of posts before that ROTJ is the weakest of the saga; and blamed its lack of tension for it. I think lack of tension is one of the issues, but a direct consequence of a bigger one. ROTJ has IMO, a lack of grandeur; not speaking vissually, but in its story. ROTS though being a regular-bad movie, achieves that.

(It's gonna sound stupid but I can't find another words to say it at this time in the morning) D'you know that feeling when you are entering the highway... you just end going up the ramp, and then it's like everything accelerates and the car is on it's own? Well that could do a good figuration. ESB is the climax of the saga. Right after that, things should have to start accelerating, and let the story be on its own; having not everything to depend on the main three/four characters. ROTS was basically about how a coup d'Etat took place and it needed several elements (characters) here and there (even the clone commanders had their roles) to make it more or less armonic and believable. Having aside Luke (like Anakin in the PT), Leia, and Han could have had minor characters, or have them mixed with other characters who also are engaged with that huge and compromising task that making the Empire fall is.

What I say is "OK, EPVI the last one, now things get massive and hopefully one or two of them will survive, this is gonna be pure adrenaline.. well wait, 40 minutes wasted on Jabba's palace in a rather minimal story compared to the Empire plot". So hope you can do your best, Spence or whoever wants to make something good out of ROTJ, and give us a better movie.
