With the final duel here, I have a lot more problems. On top of taking place in a much safer environment, Vader is beaten by Obi-Wan AND basically absolves Obi-Wan of having killed Anakin Skywalker. By not killing Vader, Obi-Wan’s no responsible for all the people Vader will kill in the future. You have to do something to address it.

This is the problem of this series to begin with. How would one tell this kind of story given the frame from the OT? I can’t think of anything worthwile.
The „Obi-Wan inflicted enough pain to his former friend“ argument is one i can live with.
