Luke is the Jedi that is returning.
From where?
Not “from”, “to”. As in “returning the Jedi to the galaxy.”
I agree that the original intent of the title is about Luke returning the Jedi to the GFFA. However, I still prefer your interpretation of it being about Anakin’s return. The cool thing (and what makes it a great title) is it can be both simultaneously! It has many interpretations that are equally valid.
