Rey being a nobody is the one ‘twist’ that actually worked in TLJ, so that would be a nah from me.
I would have been completely fine with her being a nobody if there were valid reasons and demonstrations as to how she became so powerful and proficient in the force over the course of a week or two.
Because they dont, she needs SOME sort of lineage to help explain it but even then its pretty weak sauce though it could have worked well in conjunction with her instead having raw and untrained power that is unwieldly and actually dangerous to both foe and friends and she needs the training and discipline that either Luke, Snoke or Kylo could give her to help her learn to control it.
The arguments of “what the ST needs” dont wash with me as its at the expense of the OT and those that understand its universe rules as a result of having watched it for the past 40+ years. If they want to change them and how the force works, there has to be real justification that makes sense and retains context to the original rules. They don’t just get to say “this is how it works now” and leave it at that, they have to earn the changes.
