I liked Rey Nobody and like Rey Palpatine enough but Rey Kenobi was something I was absolutely vehemently against from the start...
I remember when it was revealed she was "nobody" in TLJ I almost did a dance because they weren't doing Rey Kenobi...
Then when I learned she was a Palpatine, I was like "At least she wasn't a Kenobi"
Rey Kenobi would have been just such obvious and insulting fan service with no actual point to the story that I would've probably dropped the sequel trilogy all together...
Rey Palpatine at least has some poetry and cool things associated with it. I have no idea what Rey Kenobi would have done for the story...
