Didn't some of the crew of TFA actually come out and say that there was nothing special about Rey's parents and fans are overdoing it? I seem to remember something like that being said a couple years ago but I have no idea where to begin looking for it at this point.
I don't recall that specifically but IF that was the case, the film should not have been ambiguous about it and the filmmakers over the last 2 years had numerous opportunities to clarify it but instead chose to play off of audience speculation. They intentionally set up a mystery without actually having the answer matter and Rian saying the answer was "Profoundly satisfying" was an outright lie.
