I think George wasnt sure what tone the Prequels Movies should had George tried to make the Phantom Menace into a Political Movie but at the same time he wanted the Phantom Menace to be a Kids Movie too because of Jar Jar Binks, Kid Anakin or the Pod Racing Race etc i think that affected the Prequels George tried to make a more Complex Plot but he wanted those Movies to still have a Childish tone for Kids only Revenge of the Sith was the only Movie when George really wanted a Movie to have a “Serious” tone but failed Anakin motives for Turning to the Dark Side are not clear at first he says it was because of Padme then he said that it was because the Jedi did not understand his Power and that they were holding him back and also Lucas wanted to make the Jedi being seen as Arrogant when the Argument for why they are Selfish from Anakin Perspective is not clear or well defined the Prequels also contradict the Original Trilogy since Obi Wan is not the one who finds Anakin, Anakin is not the Already Great Pilot Person that Obi Wan told to Luke in ANH, i dont think Anakin being a 9 Year Old Kid was the Original intention and Padme does not survive Revenge of the Sith a contradiction with Return of the Jedi since in there Leia tells Luke that she remembers her Real Mother George Prequels might have been interesting but i think some EU Stuff like Knights of the Old Republic Video Games or the New Jedi Order Novels made the Jedi or the Force more Complex than George Prequels Movies are
