As for introducing Palpatine, Jake, I’m gonna be honest, that’s a really dumb idea. His introduction fits perfectly as a cliffhanger ending to TLJ. Leave it at that.
Thanks for the constructive criticism, I was just trying to show how your otherwise unaddressed nitpick was solved with that change. 👍🏻
I don’t expect Hal to change it, but moving it to the other side of the credits between acts 2 & 3 doesn’t fix the issue of a random deus ex machina being added for the villains, for me. It also doesn’t fix your issue with wanting to portray Kylo more clearly not serving Palpatine.
