Rey taking the name and inheritaing the legacy of our heroes could have been compelling, had her relationship with the legacy characters been fleshed out.
I think that was their original intention, but of course, Carrie Fisher unfortunately died. It really does seem like Leia was set up to do some major emotional/moral/thematic heavy lifting in TROS. I think they did the best with what they had to work with, but to me, this is biggest issue with the film.
