The story is really well written, from a script writing perspective anyway. A lot of pleasing circularity in the overall story.

They nailed the characterisations of the aged up heroes. They're slightly mellower, slightly wiser, but still that ragtag band of rascals.

I was surprised that Dante Basco didn't reprise his role as Zuko, but the new guy did good work. Overall, a lot more Asian voice actors in this one, which is a strong choice imo.

Some of the story beats were slightly hasty, but it retains the emotional legibility of the TV series. The animation was overall stunning, some pieces seemed to cut corners with CGI in the background but it's not overly abrasive.
