Actually, I've been meaning to ask about this. I've seen this complaint a lot, especially on the Disneyland forum. Not to be rude, but I just don't understand this at all.
Not rude at all, absolutely fair point. The issue (to me anyway) is not whether they Imagineers effectively captured the feel of a silent, deserted, war torn, rusted out outpost, the issue is whether that was the right creative choice to launch Star Wars in Disneyland.
Your comparisons to Harambe and Anandapur in AK are great examples of incredibly detailed theming that puts me in a place full of color, detail, and life. I often find myself standing there just taking it all in. The colors, open shops, atmosphere music, live entertainers, animals, etc. create a "real life" exciting, exotic experience that I want to be immersed in.
However, SWGE does none of that. It's like a static, brown backdrop that was designed for SOMETHING to happen to bring it to life, but then that entire part of the production never happened. If the land was overrun with music (including live performers like in AK), color, activity, droids, aliens, bounty hunters, etc you would be hearing very little criticism as the "backdrop" is great for telling that story.
The cantina is the best executed concept, but so few get to experience it and it is entirely closed off from the general audience, that even that has less impact then it could.
It's like they built a Renaissance Faire and then canceled all of the performers, artists, musicians, and jugglers leaving you with the sawdust, empty booths, and silence. If you haven't had the chance to see it in person, it is hard to describe the "abandoned" feel.
Star Tours (from 33 years ago) did an amazing job of putting me into the Star Wars universe and was filled with characters, music, fun and celebrated the brand, its planets, world, etc. Those were creative choices that were pure genius to bring the Star Wars universe to life in a theme park setting. SWGE, unfortunately, is just not.
