The premiere episode of The Legend of Korra leaked last week, but if you've been waiting for a less illegal way to watch the Avatar: The Last Airbender follow-up, now is your chance. Nickelodeon has decided to bow to fans' impatience by streaming the entire first two episodes at KorraNation.com,
and the second episode should be up soon as well. Let the battle between the Benders and the Equalists begin!
Edit: US only, sadly. Nickelodeon, you've got international fans out there, too!
