I've never seen Adolf Hitler as a worthy comparison to Darth Vader. But, then, at this moment in time, I don't know who would be (it's early in my part of the world right now and I've yet to have my first coffee).

Regarding Yoda's death, I've always seen it as Yoda holding on to life until he tells Luke what he has to - that there is another Skywalker (the last thing we hear him say in TESB is "there is another" so this seems logical to me).

And while the rescue of Han Solo is a sizeable chunk of the film it's also incredibly fun - the cantina scene of ANH writ large if you will. The choreography in the fight scenes is bloomin awful, though.

Irvin Kershner said that the characters move from one set piece to another and never seem to be in any real danger. I agree with him there with the exception of Luke being fried by The Emperor - although before the addition of Vader's "No. Noooo." he seemed to deliberate just a few frames too long before making his sacrifice (ooh, that's going to make me some friends round here). He also said that he felt the actors were going through the motions - well, he may be right there, too. Carrie was too pre-occupied with the old marching powder and both Harrison and Hammill had had ideas for the development of their characters turned down so maybe they were unhappy at what they perceived as being too lightweight a film. However, when Kersh says he would never have shown Vader's face I disagree with him absolutely. The moment between the unmasked Vader and Luke is extremely tender and one of the most moving scenes in the entire saga.

ROTJ has a job to do, which is to tie up the loose ends and bring closure to the story. It also serves to remind us that Star Wars is kids' fare. TESB developsthe characters and adds depth to the whole thing. That job done, we can now go back to having fun and if one word can sum up ROTJ then "fun" would be it.
