A Rey parentage reveal is needed at some point, after what was set up.
As I said for “last Jedi living in nowhere”, just because it was thrust upon by TFA it does not mean it is not a rehash.
And what if the reveal is a character we never met before? Still a rehash?
Honestly, unless she ends up the kid of the main villain who supposedly killed her dad, I don’t see how the reveal would be a rehash.
I see TFA and the ST as less a direct sequel and more a continuation further down the line with a new generation.
Well regardless of how you see it, the truth is that TFA is more of a soft remake than sequel.
I think soft reboot is a bit closer to the truth.
