I only object when stories like these are inconsistent with their own rules. I don’t care whether anything within is ‘realistic’ to our world.
I had a problem with SKB’s firing being visible the way it was since it flies in the face of a basic understanding of light within SW. The discrepancy is evident when one looks at the hilarious official explanation.
Here, jumping in and out of light speed would be expected to look like skipping a stone on a pond. It might be in a straight line, or perhaps alternating a number of directions, but this scene implies they are more or less teleporting. This is baffling when placed alongside any and everything else we’ve ever gotten about hyperspace.
By all means, and please understand me, I welcome space slugs, mysterious gravity sources, sucking up the sun gradually until it fades to night while surviving on the planet, blowing up from the Star you sucked up and turning into a planet-sized Star that looks the same, etc. However this fictional realm works, cool. But I don’t like when it breaks its own rules.
Worlds serve stories, and once the story is told the world goes away. To set something else in the same world is merely to craft a similar world for a new story.
