It’s a really great show, but if your watching in hopes of getting more of ATLA you won’t get much, but it does show things that happened to team avatar after the series ended, and has many references. I personally find the show amazing and personally just as good as ATLA but the whole thing is definitely different from ATLA, in terms of the story like and plot. It focuses a bit more on romances then avatar did, the whole show is pretty great and I’d definitely watch it again
