The prequels disappointed a lot of people but there are a lot of fans too. The reason being (in my belief) is because the movies have some really good ideas and writing in them, they're just not completely polished. Something more along the lines of a second to last draft, rather than the final. So on that note, what would you have changed? I'd prefer no complete rewrites or anything along those lines more like small changes that keep the same story. For example, Darth Maul is actually really cool in the Clone Wars. I would have had him being the person in contact with the Trade Federation and not revealed Sidious until late in the film. Kind of like how they reversed the roles for Moff Jerrjerodd and Darth Vader in Return of the Jedi.
