I also maintain that the biggest flaw with the prequels is a fundamental one: they were made with the assumption that people have seen the OT. Getting them to work in episode order requires writing them with the assumption that nobody has seen the OT.
Is that even a problem, though? I feel like no one would be upset about this if Lucas didn’t try to pedal his “Tragedy of Darth Vader” bullshit later on. Despite what George says, the prequels weren’t meant to be seen before the OT, and that’s great! Writing a story about Anakin’s transformation into Darth Vader, with the assumption that we’re not even supposed to know that Anakin and Darth Vader are the same person, would just be a contradiction that de-emphasizes the point of the story. If you view the saga in release order like you were supposed to, all these complaints about “ruining the OT’s plot twists” become completely invalid.
