May I remind you, by starting with the first three, you are cutting the legs out from under the biggest plot twist of the century...
"Luke... I am your father!"
"That's not true! THATS IMPOSSIBLE!"
(Yeah, i could probably quote that movie verbatim.)
Too bad you just used the legendary MISquote.

Vader: Obi-Wan never told you what happened to your father.
Luke: He told me enough! He told me YOU killed him!
Vader: No. *I* am your father.
Luke: Noooo! That's not true! That's IMPOSSIBLE!
Vader: Search your feelings, you KNOW it to be true!
Luke: NOOOOOO!
Anyone who says Hamil can't act needs to be sat down and forced to watch that scene over and over.
Although IMO the best out of ALL the lightsaber duels was Return of the Jedi's. You could just FEEL the way Luke and Vader were not just dueling with their weapons, but with their WILLS as each tried to turn the other: Luke to redeem his father, Vader to draw his son to the Dark Side. There was an emotional stake in that battle that the prequels never even came close to matching
