something that is also very important only Luke can see the ghosts nobody else can. And he only sees visitation by force ghosts but if Anakin was shown in commune and un force ghosted it would take on a whole new meaning to the realm of the "Force Ghosts" and create even greater mythos so I think that could be a very good thing in a way..

hm, could you explain a little more what you have in mind ?

nay, that is too complicated, such a way could only work in a novel, where everything is explained, when what why - in movies this is not very easy to convey ...

I think Anakin should disapear and thats that - for the PT, he shouldn't be the child-mass-murderer, the Empire has many killers to do the dirty work, Anakin only betrayed his kin not slaughtered them - my two cents.
