That was certainly among the most vocal complaints I remember hearing about the movie at the time (other than the moronic "Too woke!" complaints), and Wikipedia supports my memory:

> Particularly divisive was the reveal that Rey's parents are insignificant; many fans had expected her to be Luke's daughter or to share a lineage with another character from the original trilogy.

Remembering and reading the source articles, divisiveness wasn't the fact Rey's parents weren't royal lineage, it was that fans are going to speculate, and Disney did nothing on or off screen to manage that speculation. In fact, Disney fanned the flames leading up to it.

Rian Johnson: "It's something that is absolutely going to be addressed... The other part of it is there are lots of surprises in this movie and lots of twists and turns, and I really want people to experience those when they see the movie for the first time. "

Ok, so years of oh, ah, and then the big lineage reveal comes and she's just a peasant girl. Screen rant called this "anticlimatic," which is was. The easily could have managed that earlier with a decent plot and decent writing, but the whole trilogy seemed to be written by a bunch of high school students.
