Luke and Anakin’s journeys should have paralleled a lot closer than they do in the PT we got. More than just a few visual references. Their arcs should be more or less the same, up until Luke sees he’s going down the same path as Vader and rejects it in RotJ.
Both Anakin and Luke would start their path becoming Jedi for the wrong reasons: Seeking out adventure, and becoming more powerful to help fight in a cause. They’ll both get their asses kicked by the villain of the story, but Anakin doesn’t get the revelation of the path his father went down. Anakin will start to seek out the dark side, which will leave him better equipped to fight in a war than the Jedi’s pacifist teachings. He’d defeat the enemy in a reversal of the RotJ throne room. Without his “I am a Jedi, like my father before me” moment, he kills the villain and ends up at Palpatine’s side.
