I’ve always seen SW as more of a fantasy saga. So while, in the real world, it wouldn’t necessarily jive with our concept of maps (which cover everything), in a mysterious fantasy galaxy, its a bit different. Lots of spots in the galaxy are uncharted, just like lots of spots on a map of the earth in a medieval fantasy film would be, or any other sort of older setting (like the wild west or the high seas or something).
I agree. My issue is that they state that Max Von Sydow’s map doesn’t match anything in their records. Then R2 rolls out at the end, and it matches. So R2 had a map that no one else in the galaxy had. So evidently all of that space was uncharted until some mysterious person made the map and gave it to R2, apparently WHILE he was turned off. It seems odd that no one reacts to this. At least when they find Luke’s lightsaber, characters at least wonder aloud where it came from.
