"Avatar the last airbender" - Redesign

I don’t know if I’ve already told you, but I really, REALLY DON’T like live-action remakes of animated movies/series. Alas, it seems that no one shares my opinion given all the live works adapted from animated works still released. Their latest victim : "Avatar, the last airbender" !

My new pitch : in a world with a Nimona-like level of techology, the Fire Nation has more or less conquered the world. Not by force, but by influencing long-term technological and cultural advances. Bending has become increasingly rare, to the point that many think of it as just legends. One day, two children of the Water Tribe find a hurt and amnesiac golem in their neighborhood. This new trio go on an adventure to restore the golem's memory and perhaps change the course of their world.
