I don't know why Adywan would spend any time fixing the Prequels after finishing the OT. They're so forgettable. Best to count them as a lost cause and focus more time on the OT.

Further to my recent answer here I would add that they are the most broken.

You can't really change much story wise with the first two films because they are narrative speaking pretty sound movies.

Jedi and the prequels allow increasingly more room to be creative because anything you do to them will be seen less like vandalism.
