Seriously, and again, the camera work is abysmal.
I'm not even a cinema savvy enough, to spot every directing flaw while i watch a movie, but with this, is impossible not to.
Like, after they free the Earth benders in the village, there's an entire dialogue of shot/reverse-shot with super tight close ups, and at the end of said dialogue, you hear and (barely) see the earth people celebrating (in the background), while the camera stays on Aang's face the whole time; it should've had a larger shot to close the scene, showing the people celebrating, no it stays on the kid's face and then cut to whatever else.
And this kind of crap goes on throughout the whole movie.
