Here's the opening crawl, xip:
"The dead speak! The galaxy has heard a mysterious broadcast, a threat of REVENGE in the sinister voice of the late EMPEROR PALPATINE.
GENERAL LEIA ORGANA dispatches secret agents to gather intelligence, while REY, the last hope of the Jedi, trains for battle against the diabolical FIRST ORDER.
Meanwhile, Supreme Leader KYLO REN rages in search of the phantom Emperor, determined to destroy any threat to his power?"
When the movie opens with, "the galaxy has heard a mysterious broadcast," there's no ambiguity there. It wasn't just the FO who would've heard a private transmission. Palpatine was announcing his presence and intentions to EVERYONE.
That is indeed fortunate for you.
As for me, Rey (daughter of Palpatine) healing Kylo, and Ben Solo giving his "life force" to resurrect Rey from the dead, made it impossible for me to just ignore how that totally undermines the story of Anakin (the son of *the Force itself!*). His whole turn to the dark side started because he couldn't keep his mom from dying via her injuries. And then he turned all the way to the dark (and set up the Skywalker tragedy) because he couldn't think of a way to save Padme if she died during childbirth.
Anakin Skywalker - The Chosen One (with higher Force capacity than even Yoda; and with 10+ years of training) - couldn't heal those he loved, and turned to the dark side as a result. But Rey Palpatine just magically knows how to heal? And for good measure, lets have Ben Solo instinctively know how to resurrect someone from the dead.
"Sorry Anakin, you just weren't as good as these two."
Anakin Skywalker - The Chosen One - became one with the Force in ROTJ. He then chose to speak to Rey Palpatine for encouragement and guidance. He didn't reach out to his son Luke to prevent the loss of Ben Solo to the dark side, and to prevent Luke from having to go into exile. He didn't reach out to his grandson Ben to keep him from helping Snoke/Palpatine destroy five planets. He instead chose Rey. So she's the true Chosen One in the Skywalker Saga? Yuck!
Anakin didn't intervene by reaching out to his grandson. Instead, he let the actions of his grandson lead to the deaths of his twin children and a son-in-law (and billions of others). But then decided to get involved to influence Rey The Chosen. I can't justify any of that if I want to preserve the point of GL's story in episodes 1-6. For those of you who can, that's awesome; more power to you. But I can't.
Then there's the whole fact that Anakin never really killed Palpatine or eradicated the Sith.
