I sometimes think of the gravitational microlensing that magnifies planets so far away that it is unlikely to ever happen again as it was a chance alignment that just happened to be spotted by our telescopes. Like the planet that may be 4 billion light years away in the Twin Quasar.
We'd probably never be able to verify it, but it's cool to think about.
The Imperial parts were also extremely well executed. Dedra, Syril, Partigaz's actors were all on point and were remarkable complex characters. We were able to see through the inner workings of the Empire ISB, not something typically told in Star Wars stories.
