If he had stuck to his original ideas (what he had of them) for the PT and the ST ROTJ might not have been as crap as it turned out too (if there were three more films to their would be no need to kill off all the OT bad guys in one very silly film for one thing).

I am completely repulsed by the idea of having 4 films addressing the subject that is now being addressed by ROTJ. The Luke-Vader-Emperor story had to be concluded in the third film of the trilogy. Otherwise we would get four more boring films instead of a great film as ROTJ is.

New trilogy, new subject. That is how it should be and that is how it ended up.
