The prequels awful little in terms of character development or story.

It was a mistake to make them in the first place if they would not adhere to the already written backstory with the changes of Vader Being the father and Leia the sister.

Luke's story should have been continued and the story brought forward and actually see the characters mature. Otherwise its just 3 static films. And Luke never gets a love interest or actually does anything after becoming a jedi. They just roll credits.

If the prequels had to be made then we should have seen Vader hunting down the Jedi, not leave all the cool bits up to novels and EU merchandising stuff.

Hayden did not look right in the suit he is not tall enough. David Prowse should have been in there somewhere.

The Lightsaber duels in the prequels were too showy they were ridiculous. Should have been more like empire strikes back. The twirling in Sith and i have the high ground come to mind. As does the bad acting when Hayden says you turned her against me. and you underestimate my power.
