There would be lots of things to say about this movie, but I think all of it has already been said. It is a more than worthy ending for this great adventure - Lucas really did it all better than ever before.
Episode I and II were disappointments to me, although the ending of II had already some scenes in it where the spirit (or the force?) came alive again. It was the first time we saw Yoda fighting and I felt as excited as I felt when he, many many years ago, in another galaxy, taught "young Skywalker" to be a Jedi. And this time? He enters the room to confront the source of all evil and when two of the guards want to make a move for him, he just lets them break down by a little hand gesture, not even looking at them.
Everything is it the peek of strength in this movie, the legend shivering with power and within all that we have a real story. The big question "how could Anakin turn Vader" is answered in a more complex way than I have thought. No no - it is not an intellectual thriller this time, it is still the good old straight-forward star wars, but there is a reflection of Goethes Faust in Skywalkers eyes when he is listening to the messenger from the dark side.
The movie starts high up in the sky, spaceships batteling - and ends in the black and red hell of a vulcanic planet. Symbolism all around, but most of the time it is done so well that you think it is the story you are watching, not the message. And still there are jokes, the movie is making fun of itself without going ever too far (at least in I & II they went over the top).
It gets 9 out of 10, because I did not like how Palpetine was played when he showed his dark side. Everything else was what it should be: legendary.
