One of the greatest shows ever made. The insane amount of character development in this show baffles me. I never thought a televison show on nickelodeon, and that too an animated show, could ever be this good, but it was....
All the character interactions feel real, there are consequences to actions, topics like war, genocide, loss and matters like sexism are explored in a mature way and the action is possibly the most skillfully choreographed action i have seen in a while.
The music levels up any scene in this show. The slow tunes of leaves from the vines, to the heart racing beat of any action scene, to the hilarious quirkiness of momo's theme, and the grand opera epic theme of the avatar state and the opening of the chakras, it's just incredible.
The animation and art style is a bit slouchy in the first few episodes but it gets unbelievably good by mid season 1 to the point where it's outright gorgeous in season 3, making the action scenes look cool.
The deep eastern cultural themes of this show and how it shows the connection of every element i.e. Fire, water, earth and air to the nations and the world altogether is just magnificent to watch. It almost gives a sense of realism to this show, and I'll forever be grateful to the writers for this choice.
Believe me it's 10/10 worth binge watching.
