Meh, IDK. You've lost me, guys.
I somewhat understand your desire to transform the Star Wars trilogy into the serious dramatic masterpiece that it currently isn't, but is there no room for a feel-good scene? Is it so bad to end the trilogy on a positive note?
Having Anakin's ghost appear is very very different from the SesameStreet-esque reductio ad absurdum ending described above.
How would you prefer to be at the end of the trilogy? In awe? In shock? In tears?
