Rey’s vision feels absolutely perfect, better than the original for sure.
Kylo’s vision veers a bit into fanedit territory for me, mainly due to reusing so many shots from TLJ. Perhaps removing some of the shots that are clearly not from Kylo’s POV would help. I agree with Hal that if there’s a way to use Luke for haunting purposes, perhaps the closeup of his face in his duel with Kylo, that would be ideal.
