I feel like the prequels would absolutely not be “ruined” if they were written well in terms of portraying Lucas’ intentions. In fact it’s kinda laughable IMO to say that making the audience care about and sympathathize with the Jedi, show them as kind and compassionate monks would make the movies worse. Imagine how much more heartbreaking Order 66 would’ve been if you actually cared about Ki-Adi Mundi and Plo-Koon, and the impact that Anakin betraying them all would have. The messages about not becoming too possessive of people and being selfish in your relationships wouldn’t be muddied. People would realize what Anakin actually did wrong instead of blaming the Council for his actions. You wouldn’t have people saying that the Sith “aren’t actually that bad”, despite the fact that the guy who wrote the Sith code openly said he was inspired by Mein Kampf and Lucas compares Sidious to Satan, that “bringing balance to the force means destroying the Jedi too”, or “the dark side isn’t inherently bad to use” (yeah, it is).
