Avatar The Last Airbender. An animated series with a complete story arch that takes place in a unique world. The characters are very relatable and have great development over time, even the villians are better than what most shows have. The animation is sophisticated in the way it is used to help tell the story, and the story is wonderful, it hooks you in from the intro:
“*Water. Earth. Fire. Air. Long ago, the four nations lived together in harmony. Then, everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them, but when the world needed him most, he vanished. A hundred years passed and my brother and I discovered the new Avatar, an airbender named Aang. And although his airbending skills are great, he has a lot to learn before he’s ready to save anyone. But I believe Aang can save the world.”
