You ready for this? The most unpopular of opinions? You know what would be super cool and kind of dope for the ATLA liveaction show? No romance. Or heavily downplayed romance. No Kataang. No Zutura. Sokka and Yue can stay but then give the poor boy more time to heal after her loss.
They are kids. Even Zuko and Sokka, the older members of the Gaang who are romance ready, have heavy psychological scars. And are basically child soldiers.
What if we super focus on friendship and platonic support and leave all that sweet, sweet, romance for after the war is finished? When everyone is ya know. More legalish. And emotionally stable/healthy. And the world isn’t two steps from hell.
