The thread was this.
"Hypothetical: What would you KEEP?"
I would keep nothing of the prequels. Seriously absolutely nothing about them stands out as being very good or on par with the original trilogy. Not even John Williams music saved the films.
If they could be redone in the style of the classic trilogy following the established Canon as it was at the time Return of the Jedi was released. The outline Lucas and Kurtz worked out in the seventies plus the 2 changes the vader being the father and leia the sister. That is it.
And work from there. The prequels contradict Lucas earlier trilogy to such a degree he finds the need to re-edit them and subtitute things to make them fit the prequels. The truth of the matter is to completely fit the prequels the original trilogy would have to be redone in the spirit of the prequels and entriely reshot.
Some fans have gone so far to say they would support a films 1-6 saga reboot and reimagining. I would not go that far myself. These people want Star Wars to get the same treatment and redo the Bond, Batman and Star Trek franchises have.
