I would have liked Revenge of the Sith better if they had just handled Padme's death a little differently.
As it is: she dies because she has nothing left to live for even though she's giving birth. What? Screw you, lady! You are now the most unsympathetic mother ever!
Now, take the same scene. Anakin Force Chokes the Hell out of Padme, maybe even worse - and of course she's mortally wounded, perhaps internally, and she's taken away after Anakin leaves. Now we have her at a point of injury where even Star Wars tech shouldn't be able to realistically save her - she's way, waaaay past the point of no return. But there's an inversion of what's in the movie: they talk about how she should already be dead, but she continues to live as she goes into labor. She gives birth to them, remarking that these children are the last symbols of the love that she and Anakin shared, and naming them accordingly. She dies only after giving birth because, until that point, she just would not allow herself to die.
It wouldn't have been great cinema but it would have been a much better tear-jerker than what we actually got
Also I like Empire Strikes back best. When I was young I liked Return of the Jedi for the battle over Endor - not Endor itself.
