You remember Avatar: the Last Airbender, right? Sure you do.
If you haven't managed to see it, it combined a fascinating new world, compelling characters, great animation and a complex story involving martial artists who huck huge amounts of elements at each other. What's not to like? Go watch it immediately.
Then a live-action movie came out. It was awful. Seriously. You're better off not asking about it.
The only plus side to the movie is that Nickelodeon decided to give the original creators of the show the chance to do a sequel series, with a bigger budget no less. And so The Legend of Korra was born.
Set 70-odd years after the events of the first series, the new show focuses on Korra, the new Avatar after Aang. A native waterbender, Korra quickly mastered earthbending and firebending, though airbending eludes her. Probably because the spiritually-focused discipline clashes with her brash, impatient personality. She also has a huge polar bear dog named Naga.
To learn airbending, she travels to Republic City, a thriving metropolis founded by Aang and Zuko after the events of the first show. It's technologically advanced -- think 1920s Hong Kong -- and a utopia for all four kinds of benders and non-benders alike. Er, that's the theory, anyway.
Her airbending teacher is Tenzin, one of Aang's sons. He's patient, focused and voiced by the awesome J.K. Simmons. His kids are Jinora, Ikki and Meelo, who are... well, less patient and focused.
Along the way, Korra meets Mako and Bolin, brothers who compete in pro-bending. Mako, a firebender, is stoic and controlled, while Bolin, an earthbender, is goofy and excitable. Together with Korra, they compete as the Fire Ferrets, possibly named after Pabu, Bolin's fire ferret.
Lin Beifong is Toph's daughter, only she's less blind and more of a hardass. She leads Republic City's police force, who are metalbenders to the man.
Remember how I said Republic City might not be the utopia its creators hoped for? Here's one of the reasons. Amon is the mysterious and charismatic head of the Equalists, a group dedicated to opposing benders of all type, since the Equalists feel their massive power oppresses non-benders. And he's got the means to do it too -- not only does he have a large force of chi blockers, who can temporarily block bending, and an array of high technology at his disposal, Amon has the ability to take a person's bending away. Permanently.
This is Tarrlock, a member of Republic City's council. He's interested in tackling the Equalist problem head-on... very interested, in fact.
Can Korra bring balance back to Republic City? Can the Fire Ferrets stay competitive in pro-bending? Will Korra ever figure out airbending? What's the secret to Amon's power? And when will Meelo learn what is and isn't a toilet? Stay tuned to find out.
Before you ask, there will be a second season of 14 episodes after this one, but an airdate hasn't been announced.
