Sorry, but this ain’t a 30’s serial. It’s 2020, audiences expect more complicated storytelling than just “he escaped.”
Lemme rephrase this: The Master always escapes.
But the whole Chosen One thingy is about him destroying the Sith and bringing balance to the force. If he didn’t actually kill the last Sith, that makes the whole thing seem really stupid. I know some people didn’t like the prophecy, but that doesn’t mean you can just ignore it and pretend it never happened.
Idk. I like the Prequels but the Prophecy I can take it or leave it. Doesn’t really do much either way.
Anyway, Palpatine coming back as a clone feels super cheap and cheesy. Besides, Palpatine is one of the two most powerful mortal Force users in the Galaxy (the other of course being Yoda). And I ain’t talking potential and mid-chlorian counts, just in terms of what they are capable of. Therefore, it stands to reason that it is plausible for him to survive being thrown down a reactor shaft. Luke survived such a fall no problem. Yes, there was also Force lightning, but it was his Force lightning, so it’s reasonable to suggest he had enough control over it to at least not kill himself. Then again, that’s how he dies in TRoS and has his true face revealed in RotS, so who knows. But hey, points for poetry for having every trilogy end with Palpatine electrocuting himself.
