The Legend of Korra is an American animated television series, that premieres on the Nickelodeon television network on April 14, 2012. The series is a sequel to Avatar: The Last Airbender, which aired on the same network from 2005 to 2008, and is currently set to run for 26 episodes
it's disappointing a little, the idea of the republic, and cities with buildings and that stuff, i miss the old version of avatar, it was unique, but here it seemed as if they were trying way too hard, i wished they would continue with the aang arc. the legend of kora is missing all the good ol character we know n love.
but, all in all it is a pretty impressive show and i would like to see where it goes, and i recommend all avatar fans to see this :)
