Now that The Last Jedi has been out for a while and Star Wars fans have had time - and repeat viewings - to pick away at the details, the people tasked with making sure there's a well-thought explanation behind every story beat and visual cue are seeing more and more questions about all the hundreds of little things that matter.
The last Star Wars movie premiered a few days before Christmas, conquering the box office on opening weekend and in the weeks that followed.
On Episode IX: "I would very much like to complete that".
Mark Hamill (himself) has been singing the praises of Ireland's Wild Atlantic Way and Skellig Michael, which both have starring roles in billion dollar blockbusters Star Wars: The Force Awakens and Star Wars: The Last Jedi. The idea that you can pull an object to your hand probably makes sense once you learn you can use the Force to strangle somebody, but there was no reason to believe you could use the Force to strangle somebody until we saw Darth Vader do it.
"When I read [The Last Jedi] before [The Force Awakens] came out, I said 'what?!" and called JJ [Abrams] or Rian [Johnson] to say, 'Are you guys aware of this?
Of course Kylo Ren isn't confused by the presence of his grandfather's lightsaber.
Odds are Rian Johnson's explanation either wasn't necessary or it wasn't enough.
As for why Kylo Ren didn't notice that Luke was using the same lightsaber that had been destroyed during his confrontation with Rey, Johnson noted that the new Supreme Leader would have been blinded a flash of light and knocked unconscious during their showdown, therefore he would not have seen the weapon being damaged. He draws his lightsaber, and Luke Skywalker does the same. This will probably be explored over the next couple of years as Star Wars 9 nears completion. That doesn't mean you're going to agree with the choices he made artistically and narratively, but he made them consciously.
