A something I would personally like to see changed is Obi-wan calling Anakin Darth during their final battle. I think it deserves a more personnal acknowledgement between them, "You can't win Anakin" re-affirms his previous loss and lava ordeal, along with "Only a master of evil Anakin" would fit eerily well after the child killing scenes in ROTS (along with all the other evil stuff he's probably been up to since then).

That would be disastrous, as it would make no sense unless the viewer saw the prequels before seeing SW.
