The Legend of Korra premieres on Nickelodeon on April 14th, but if you can't wait to see the Avatar: The Last Airbender sequel, I've got great news: You don't have to, because the first two episodes are currently available on iTunes for free in HD and Standard Definition. The series takes places 70 years after the original, and follows Korra, the next incarnation of the Avatar, on her adventures in the metropolis of Republic City. SPOILER ALERT: This show is really good, full of gorgeous animation, surprisingly fierce action, and a courageous, impulsive, funny and fully-clothed female protagonist that makes you want to look at most superhero comics and say, "Is this really that hard?" I don't know how long this deal lasts, so grab it now!
