One idea I’ve been thinking about for the past few days is to push the “Luke’s Moment” deleted scene all the way to the point where Rey leaves Ach-Tu. I think that a lot of the issue people took with Luke’s characterization in TLJ was due to how bitter and dismissive he seemed. Obviously he ends up being the Luke Skywalker everybody loves, but we never really see that transition take place. He’s constantly bitter for 90 minutes, has the scene with Yoda, and then is suddenly the hero everybody has dreamt of. But if you move him having a moment in his hut to the point where Rey confronts him about how he turned Ben to the dark side, it’s a lot more meaningful.
This is an interesting idea and I’d like to see it implemented.
