Absolutely. “Lightspeed moves at the speed of plot” was a phrase created to explain how Empire Strikes Back’s timeline made any sense (it still doesn’t, really. Neither does the ‘12 parsecs’ retcon they made w/ Solo’s boast) and the thing I keep coming back to is that none of these logic gaps and nitpicks would matter if the story was good at distracting you from them. Or if the story was good (and executed well on top of that) at all.
It’s not as if these problems were explicitly addressed IN the story that it’d make the story better. That’s the real problem. Even if Merry’s whole point in the movie was to stand over someone’s shoulder and explain how Lightspeed Skipping made sense, or how the necklace got located so quickly, it wouldn’t make those scenes any better. Sure, they’d be more logically sound, but that’s not worth much if you’re not emotionally engaged, and Rise of Skywalker isn’t great at that, so all the logical leaps being made just become all the more glaring.
