The way you worded that really does strike a chord with me, because it made me realize just how quickly all the settings in the show go by. There’s a kind of lack of personalization or over-familiarity between the characters and the settings. Basically, none of the places felt like the characters really lived there? This is, of course, coming from someone who hasn’t watched the show in 6 months and only watched it once, but other than the training room there aren’t really any locations in the show that I could put a name to. There’s “place where x happened” or “place where y happened”.
My viewpoint is also contrasted by the fact that I’ve been watching Star Wars Rebels (for the first time, no spoilers please) and their ship, the Ghost, is so lovingly designed and personalized, I feel like I could wander it like it’s a real place. Not just because of the paint and moded cockpit chairs and funky couches. There’s a certain weight to pretty much every location. Time spent in them and how they interact with the scenery matters. They aren’t just backgrounds, most of the time they’re downright jungle gyms.
I disclaimer all of this with: I do not know what it takes to design and render 3D spaces and what kind of pipeline--and inter-team communication--is required to successfully give your writers free reign over the scenery as well as the characters. Even in-animate 3D models that are going to move need rigs and stuff
