The dialogue is the problem with the Prequels. It looks good, the stories track and all nearly fit into the wider Star Wars universe, it’s just that George Lucas has no idea how actual humans communicate. There was also an absolute tsunami of 3rd party content around the Prequels from comics, video games, YA novels, TV shows, and toys that cemented the Prequels into the cultural Zeitgeist that Disney was completely unable to replicate.
