I became interested in this show after watching the disappointing first season of its successor, The Legend of Korra. I wondered why people loved it so and doubted it would impress. Well, thank God, I was proved wrong!

This is a fantastic program, one of the finest fantasy series I have ever seen. The characters and their development are finely crafted. The world-building is nothing short of glorious. And though the story is your basic "chosen one fights an evil empire," the show goes beyond black-and-white morality, with characters wondering about the moral implications of their actions.

It's a shame Nickelodeon or any other channel has not had more animated fare like this. Sure, there was Korra, but the writing in that devolved quickly, and I only got a little bit into the second season before I gave up on it. This show is golden and should be seen in its entirety at least once if you love fantasy or adventure.
