If the films need to pick up one thing from the PT it's Padme.
Luke has had his relationship with his father dragged out over three films.
The character of Padme kind of rolled into the dirt in ROTS.
Wouldn't Luke want to know more about her?
Wouldn't Leia become closer to her fragmented memories of her now that the Empire is gone?
If the OT was about absent fathers I think this one should be about absent mothers.
Both are mythical tropes and it would be interesting to explore the Star Wars universe from a more female perspective.
