In Episode II and III we never see Anakin Skywalker as a character, the good fireind of obi wan seduced by the darkside. An essentually good perosn forced into making hard choices that destroy him.
The whole time he is Darth Vader Anakin never shows up.
He was shown as a caring person in Episode 1 even if annoying, and not very well fleshed out as a character because he was a little kid.
The Jedi are not guardians of justice they Are amoral douchebags in the prequels. Portrayed exactly as you would imagine a corrupt ruling body of a religion would be.
Obi Wan and Yoda are portayed as dunces, and Padme is a compete retard or worse in II and III by making excuses for genocide. Nothing like Princess Leia. Except for Episope 1 we never get to see Anakin Paralled with luke's jounrey, story.
Basically the characters and characterizations in these movies could have been fleshed out and really good and complemented the original trilogy and instead they make you hate the characters in the oot and have contempt for them, especially yoda and ben kenobi.
