Yeah but that comes out of nowhere and isn’t a fitting conclusion to what began in The Force Awakens. She needed to grow past the shallow need to fit in and have a father figure, and become a whole person. Instead it’s just regression.
The name Skywalker is a legend by the time we get to TFA, and by the end of TROS it makes me feel like anyone can be a ‘skywalker’. She carries on the legend at the end of TROS, she is the ‘Skywalker’ that rose up to destroy the Emperor. It’s a story that will be told by others, just like we see at the end of TLJ when the kids talk about luke like a mystical creature.
I can completely understand your standpoint on this, and i know her carrying the name is a very divisive thing.
