I watched it when it first aired and I rewatched it a second time around 8 years ago. Characters and writing were great. Just never felt amazing, like something I'd rank above other shows I've enjoyed. I don't remember the world building being that good per say. Better than a lot of other shows but not really deep or focused.I wouldn't really say the show had good world building. It was more of "Hey, this is the world". I mean, there's a lot of inconsistencies with lore. Avatar was apparently an "avatar" for the spirit world. Which obviously isn't the case. They also retconned a few things with Korra. But on the other hand; "No, it just says bear".
