Apologies, I totally spaced on Tatooine and Bespin. It's been a while since I saw it. Both kinda odd choices though. Wouldn't Bespin have been either taken over by the Empire or simply abandoned after ESB? And I can't really imagine the people on Tatooine giving much of a shit about the Empire.
I guess I just don't see the point. There aren't any characters we care about or even know on those planets. There's never been any indication they've been struggling against the Empire themselves (especially Tatooine), and it doesn't even look like they've suffered at all. Naboo is just as idyllic as ever. If we never see them struggle against the Empire at all (I guess Bespin is the possible exception), why the hell are we supposed to care?
It kind of reminds me of the planets Starkiller destroyed in TFA. In ANH, destroying Alderaan was really important. Firstly, you get that great scene with Tarkin tricking Leia and her reaction to deciding between her home planet and the Rebellion (sort of). You get a closer glimpse at those characters, and it means something when the planet is destroyed because we know how much it means to Leia. We see how truly awful the Empire is, and we also see the effect this has on Ben to hint more at how the force works and why it's important, and destroying Alderaan forms a vital plot point because it's what brings them to the Death Star in the first place.
Then in TFA its just a bunch of random planets. Apparently they are "5 planets within the Hosnian System", which we've never encountered before. Even though 5 planets go, there's no real emotional resonance because they aren't connected in any meaningful way with the characters or the events of the story.
TFA Starkiller planets and ROTJ ending planets, I think it all comes down to establishing no real reason why we should care about these people.
I know, right! He looks super creepy - it's almost a leer. Looks like a deranged killer ... well, I guess that captures Anakin.
