Lucas's treatment of this scene is inexcusable and cannot be justified.
We have Shaw's body with Hayden's head bobbing around on top of it. The Hayden footage could be from ROTS or it could be Hayden in the canteen. The point is Lucas cares so little for these films, the story and the fans that he does something so lazy and stupid.
It is bad enough how the younger ghost changes the redemption story we have all grown up with. But THIS??!!?
Lucas really is taking the piss.
