Hmm, that seems very meta. Initially it wasn’t unusual for the audience to speculate on Rey’s background or connection to established and well known characters in the story.

I wouldn’t have minded if Rey would have been set up either as Luke’s daughter or one of his students from the start. Otherwise it seemed like Disney tried to mold Rey as their version of Luke instead of creating an original character with an original backstory.

Meanwhile I have not seen that argument pop up regarding Jaina Solo or Ben Skywalker in the EU/Legends. Both characters are their own, and their last names do not detract from their own character arcs.
