Oh I agree that Rey's parents are nobodies.Not everyone is a liar either. I'd rather not go through my life thinking people are lying to me on a constant basis. Already lived 10 years of that life.
I'm just saying when a movie is running in the theatres, people working directly on said movie probably won't say anything to directly compromise the image of it, unless they really really hated it.
Except Mark Hamil apparently. He didn't seem to care.
