Part 1 feels very free form, the narrative naturally extends onwards and it doesn't feel like there is any real overarching plots involved yet which makes sense as this is early doors for Kishimoto and there's time for that later. It may also explain why Part 1 is preferred over Part 2 as it feels more organic and less scripted. I think after the first clash at the Valley of the End heralded a change in Kishimoto's approach to his story, he did say that he had envisioned an ending for the story where Naruto and Sasuke would fight a final time at the Valley and now with this endgame in mind there is a very noticeable change in the structure of the plot.

It becomes more focused on a certain few characters, things like prophecies and reincarnations get included and the tone overall shifts as it becomes clear Part 2 is centred around the individual journeys and growth of Naruto and Sasuke. Madara then serves the middle ground for these two so that they can meet up again in preparation for the final battle i.e. he is the crossroads which allow the paths of the two main characters to intersect. Unfortunately, due to not being able to envision a way to defeat Madara he swiftly retconned out of his role in the story and replaced with Kaguya (which we all know was a terrible decision) but her purpose is still the same as the crossroads.

From this it's clear to see why Part 2 is normally seen as inferior, it suffers from classic Shounen syndrome where the circle of plot relevance shrinks as more and more characters are shunted out of the limelight for Team 7 who arguably are actually the weakest characters in terms of actual development. There's also the fact that the show goes from being about defying destiny to achieve dreams to literally all about destiny (guess Neji in Part 1 was right after all).

Linking this back to the current conversation, Part 1 is early doors which means the origins of the Sharingan were not fleshed out into the form we saw them in by the ending of the series and that's just a fact of story-telling.
