Her suicide bomber sister also seemed more interesting story-wise. They could do "Suicide Bomber: A Star Wars Story" and expand on her there.
Rose was just "WOW THESE HORSES ARE AMAZING!" and shit writing. Like, they could cut Rose, the entire subplot of the casino/code-breaker and just have it be "shit, our shields are being hammered hard and our gas that generates it is getting low..." and nothing would've changed.
The the entire "new trilogy" has been 0/2 for me so far.
