Speaking of the Death Star II, I always thought it had sorta a lame reveal. From what I remember you first hear about it in the opening crawl of RotJ, nothing too exciting, like "Whoopdy doo, the empire got a new one..."

In my opinion (I'm guessing many of you will disagree) I think it should of maybe appeared at the end of The Empire Strikes Back, so now it's even more of a cliff-hanger, like "Holy S#*&, the rebels are screwed". (Using the footage from Revenge of the Sith maybe) But who knows, maybe if it's put near the ending, it would ruin the flow.
