Zuckerman returning is the best news here, because the soundtrack is part of the identity. Without it, the movie would already feel wrong. My main concern is the plot about saving airbending culture again. We already know the outcome from Korra, so the tension depends on how personal it feels. I want to see Aang struggle as an adult, not just as a symbol. I am also curious how Katara and Sokka are written now that they are older. I do not need them to act like parents, but I want maturity. The streaming-only release is annoying, but I understand why Paramount is doing it. They want control of the brand. As long as the animation looks good and the music hits emotionally, I think fans will stay. Avatar has survived worse adaptations before.
