Okay so I think we all agree introducing Palpatine at the start of TRoS was a mistake. But what are the alternatives?
Introduce Palpatine at the end of TLJ.
Introduce Palpatine at the end of TRoS.
No Palpatine at all (good luck).
Most of these options have been explored, but I haven’t heard anyone consider moving his reveal to the end of the film. Cut all of Kylo’s scenes at the start, and change the Resistance dialog to refer to Palpatine as dead when they talk of his fleet. Then Rey shows up on Exegol and guess who she finds?
I delayed Palpatine until about 35-40 minutes into TROS: Resurgence. It works best at the end of Act 1. I set it up so after Ren lets Rey escape from Pasaana, Palpatine threatens to turn the fleet against Ren, and then Ren reacts by going to Exegol to kill/threaten Palpatine.
