I like the ending, feels very organic & has a big BttF Part three vibe to it (“Your future isn’t written yet, so make it a good one”).
From a technical standpoint, Rey vs. Palpatine is also well-done, but I’m curious about the context in the film itself. I appreciate wanting Rey to be a stronger character & not needing help from anyone, but against Palpatine, I worry that that goal would make her triumph feel unearned. If anything, the lack of Jedi just heightens the feeling of “how do we know Palpatine won’t just come back a third time” that was present in the theatrical cut.
