"Both Nickelodeon shows take place in a fantasy world where people can control one of the elements—water, earth, fire, and air—with the exception of the Avatar, a reincarnated hero who masters all four," write Danielle Hewitt and Daniel Schroeder. "Avatar: The Last Airbender follows Avatar Aang, a goofy young monk who awakens from a 100-year slumber to find the world consumed by colonialism and war. Avatar: The Legend of Korra follows his successor, a more rugged teenage Avatar struggling with her role in an industrializing society with complicated politics. Though The Legend of Korra is generally considered the more controversial of the two, each series has its own unique strengths, leaving those in the in-between camp wondering: Can’t we all just get along?" ALSO: The unaired pilot for Avatar: The Last Airbender is now available on Twitch.
