one thing, there would be no luke or leia without the love story, they are not test tube babies.
another thing, Ep III will probably be like this...
SPOILERS!!!
as you saw in Ep II, ani got his hand cut off by Duku, so therefore the start to his transformation to machine... a good reason why he lost the battle.
also, now that the republic has granted emergency power to palpatine, he can at any moment, destroy the republic and reveal himself as Darth Sidious... well now Emporer Palpatine I guess.
trade federation is soon to be destroyed, they won\'t last long in Ep 3...
Luke and Leia MUST be born, and given to Owen Lars, Anakins BROTHER...
Clone Troopers will turn into imperial storm troopers.
Amidala\'s fateful death... which will probably lead to his turn to the darkside and his allegiance with Palpatine.
END SPOILERS
Ep I - Friendly Lovable, happy go lucky
Ep II - filled with emotions of love, anger, and frustration
Ep III - (I assume) Dark, saddening, EVIL
Ep IV - uplifting, everything turns around type movie
Ep V - once again dark, revealing, dark side wins
Ep VI - a good happy ending, emotions flying
I know it might be hard, but I want a movie that sorta puts them all into perspective.
