I know Adywan said he's keeping the SE celebrations at the end of ROTJ, but in my opinon they just don't make sense.

First, the Rebels didn't have their forces spread out around all those locales to liberate them from the Empire, so having all the planets celebrate at the same time seems implausible. One could argue that the Emperor controlled through the dark side all his forced throughout the galaxy, so when he died the imperial forces were easy to defeat, but still seems unlikely.

Second, what does Tatooine have to celebrate? They were ruled by the Hutts, not the empire, and they were ruled by gangsters even when the Republic was in control in the prequel trilogy. What does the defeat of the empire mean to them?

Third, we never really see what impact the Empire has on regular people, so seeing celebrations by anonymous groups other than our protagonists just seems trite.

But if Ady wants to keep 'em, that's OK. I'm sure his version will be better than the SE no matter what.
