I confess I haven’t been following this thread, but I have strong feelings about a TRoS edit.

I think Hal9000’s “Rey Nobody” edit is great and should be the foundation upon which future edits are built. However, there’s still a lot that’s broken about TRoS, so below are ways I would attempt to fix it:

First, Hal’s Act 1 & 2 are really strong, but Act 3 is still where it falls apart. Palpatine is a genius and a master manipulator, yet his motivations are completely confusing and nonsensical in TRoS. Act 3 should be streamlined in order to be consistent with this keen intellect as demonstrated in previous films. Quite simply, he should be aware of the Dyad and is merely trying to lure both Rey and Kylo there so he can absorb their powers. He lures Rey through her need for belonging. As it stands, it’s Palpatine who is surprised and caught with his pants down. It should be the opposite so that Palpatine always has the upper hand (until the very end, of course).
Second, Kylo needs to be a stronger villain. Kylo’s threat should be maximized because TLJ set him up as the main bad guy of TRoS. The idea from the outset that he was being manipulated all along makes him look weak and pathetic. That Kylo and Palpatine are trying to outplay each other should be obvious, but it shouldn’t be so obvious that Palpatine is winning. Ideally, it would even be best if Kylo and the Knights of Ren played a hand in cloning Palpatine, but that would probably be too ambitious of a change.
Lastly, the “whiplash” moments of the film should be diminished or removed, i.e., Chewie’s dead then not, C3PO has his memory wiped then restored, Kylo’s dead…then not…then dead…then not…then finally dead for good. I mean, seriously? Not only does this nonsense make the film feel janky and unsatisfying, it also makes it feel as if there are no real stakes.
