I feel there's a massive rigidity to Star Wars fans. It's probably why I didn't enjoy the prequels as much. A lot of what happened on screen didn't jive with what I had been told in the OT. I never saw that Obi Wan and Anakin were "good friends". I didn't really see that Anakin was seduced by the Dark Side in so much as he was desperate to save the woman he loved at any cost. Yoda seemed to be a totally different person than what he was in the OT. I am not a fan of twirling, Tasmanian Devil Yoda with a lightsaber.
But you know what, ultimately who cares? It's George's work and he's been making changes to it for decades. That's the thing, the original movie was lightning in a bottle. So there was no real blue print where Darth Vader was originally Anakin or Luke's father. That didn't come about till Empire's 2nd draft. Leia wasn't Luke's twin sister until the Jedi 2nd draft. George still had plans for a 2nd trilogy where Luke's sister was on the other side of the galaxy and the Emperor would appear in that. He then decided he didn't want to keep going so he truncated it all. It was all fairly fungible and the Clone Wars were designed to fill in the gaps.
