TheOdo your explaination is good but you did not answer how you will attempt to accomplish the "threat" with any scenes breakdown like pruposed changes so it would appear that the empire is spread thin across the galaxy.... Or How do you intend to show the oppression in the galaxy?
How do you even plan to show the emporer as a dictator? I am referecing his arrival at the death star where pretty much all He and Vader does is talk about is Deathstar being completed and Luke? and then it's the same again you have not thought about it....Vader travels from Corusant To Endor to witness lukes pressence flys back to corusant to tell the emporer then goes back to endor to get luke to bring him back to corusant.... Sorry man I'd rather watch the original...
I will say this to you... I have already thought about it before and It is not possible to make a good movie and do this idea.... But go ahead and prove me wrong and good luck
