Disney Star Wars canon can be described as Swiss cheese.
Ehhh. It’s been, save for production errors (editor notes not getting passed on corrrectly, etc), the changes to the the Siege of Mandalore Arc, and JJ not giving a shit re: Poe’s backstory, pretty consistent, IMO. Nothing on the scale of… say, Dark Empire 1 completely ignoring that Leia already had two children because Timothy Zahn wouldn’t let Dark Empire be set prior to the Thrawn Trilogy and thus it having to be moved after the Thrawn Trilogy last second, or Dawn of the Jedi prominently featuring Twi’Leks and Xabraks thousands of years before either species came into existence.
At there very least, there’s been much less need for post-facto patchup jobs, like the Essential Reader’s Companion acted as (bless Pablo Hidalgo, lol. Legends would have been infinitely less functional without his hand in it,) and it’s felt overall much more thematically consistent to me, but you’re entitled to your opinion. Legends continuity only looks clean if you read it on Wookiepedia or in one of the guides. I love it to death, but without the smooth-over jobs done by Pablo and co, it’s… well, it’s like swiss cheese.
