There is nothing inherently sexist about Mary Sue. To me the term conjures notions of a lazily conceived character. Ray’s fully realized messianic chosen oneness is reminiscent of Anakin Skywalker in the PT; another unlikeable, unrelatable and flat character. One of the best heroines ever devised, in my opinion, is Beatrix Kiddo. And while she was a fully formed character when we met her, she certainly did not get there without her trials and tribulations which we get to witness in flashback form.

The very idea of messiahs are antithetical to the every man nature of the original trilogy which are the bed rock of the Star Wars universe. To claim otherwise would be to place the PT and the ST in a position more true to form in Star Wars lore with the OT as some bad outlier. The supremely gifted force user is a revisionist construct that never really fit in with the OT (IMO) and seems to have come from the expanded universe.
