So... Rey's parents...

We know that one of them was Sheev Palpatine's child. Umm... huh?
If Palpatine had a kid then surely he would have either raised the child as a Sith or had the child killed; probably the latter. In the Original Trilogy it's stated that any offspring of Anakin Skywalker would be seen as a threat, which is why the twins' existence was kept a secret from Vader and the Emperor. And indeed when the Sith discovered the Luke was Anakin's son, Palpatine initially wanted him dead, but it was Vader who suggested and convinced the Emperor that Luke could be a powerful ally if he could be turned to the Dark Side of the Force. And even then, there was only ever two options for Luke -- become a Sith or die. Surely Palpatine would have at least held the same standard for any of his own offspring.

"Maybe Palpatine's child was raised as a Sith, but just like Finn and Jannah, s/he broke free of his/her brainwashing, then ran away. After which s/he got married and had Rey. Long after Palpatine's reported death, they started a family and lived together for a few years, but then when they discovered that the Emperor being resurrected and hunting them down, they went to Jakku and abandoned Rey there for her own safety. Then they were discovered by one of Palpatine's followers (Ochi) who killed them with that Sith dagger."
Uhh... sure. I guess that could work. But the film never explains this. For no apparent reason there seems to be a generational skip between Sheev's kid and Rey. Huh? That's kinda like jumping from Anakin Skywalker to Ben Solo and entirely skipping any real exposition on Han Solo and Leia Organa. Ya what?

Am I the only one who thinks that they might've been better off postponing the release of this movie by at least a year? Release it in late 2020 and allow time for the story to be better perfected. We know that we lost Carrie Fisher after The Last Jedi, so fans will understand and forgive just a single year time delay (and any who don't aren't worth listening to).

P.S.: Just watched the Rise of Skywalker Pitch Meeting video which is hilariously on point.
