Where is Kelly Marie Tran?

Rose was a big character in The Last Jedi.  But it upset fans to see a new diverse character.   They even harassed her off of social media.  Then, JJ Abrams came back.  You'd think he'd keep her as one of the main characters.  He did not.  He did the same as Lucas did with Jar Jar.  Pretty sad.  It also hurts the movie when a director does not challenge the viewers.
