The Legend of Korra: Book 2 premieres Friday September 13 at 7pm on Nickelodeon! It was not to long ago when Nickelodeon was a channel I would not expect anything worth watching but the last couple of years they have really taken creative chances and milked those successes to incredible extremes!
The Legend of Korra: Book 1 recent was released on a single Blu-Ray collection. I strongly recommend you pick it up if you have not. It is amazing! This is all based on that you already saw all 3 seasons of Avatar the Last Airbender. If you have not seen Avatar the Last Airbender I recommend you jump onto Netflix or Amazon because the show is an amazing watch.
