I think if they felt Palpatine had to return in some form, I would’ve preferred the conflict would’ve centered around a Sith cult trying to resurrect him, and the protagonists are trying to prevent that
Having only seen TFA, wouldn’t have been better/made more sense for Kylo & the Knights of Ren to be up to this in the 2nd film & then conclude it in the 3rd?
This seems to be the way to do it & I gather this isn’t what it was done.
I mean, that’s the thing with bringing Palpatine back. If they were going to do it, they either should have done it right away or made hints they were gonna do it later. But it was done last minute, so no.
