Remake the Prequels?
Now that J.J. Abrams et al have revitalized the Star Wars franchise, perhaps the next trilogy should be a complete overhaul of the prequels. Tell the story of how Anakin became Vader, his relationship with Obi Wan, the fall of the Jedi, and the rise of the Galactic Empire in a coherent and interesting way.
I'd love to see Abrams undo the damage Lucas did, and trust he'd offer a believable reason for Anakin turning to the dark side and abandoning the Jedi.
