Luke’s sacrifice in Last Jedi is beautiful as is his letting go of his fear. The scene where he fades into the force facing a rising sun is palpable.
And its all undone in Rise of Skywalker by bringing him back to lift the X-wing in an unnecessary scene.
Rey already had the training she needed watching Luke fail according to Last Jedi, but all of a sudden we need Leia to train her. Leia suddenly a Jedi Master who never was even a Jedi Knight.
These movies don’t work in sequence.
You mean like Ben’s sacrifice in ANH was undone by him coming back in TESB and ROTJ to tell Luke things Yoda could have told him? Luke coming back as a force ghost was pretty expected and in keeping with the past. In TROS we see the Jedi Master that could have been and he is great. And I don’t see what is wrong with Leia having been trained and being able to train Rey. It answers that lingering question from ROTJ about why Luke wouldn’t have trained her. He did, but she had a vision that it was not her time.
And Leia is the one who brought Ben Solo back to the light, not Rey. Rey stabbed him and gave Leia the opening and Leia did the rest, like his vision of his father.
