This bugs me cause Wan had Avatar powers but he was the first so he didn't have the powers of past Avatars. So really Korra isn't that powerful. She's about the same as Wan because they defeated the same villian with the same power situation.
"Avatar: The Legend of Korra" - Korra. One of the reasons why I love the anime type style of animation is because it allows for such a great range of facial expressions I don't really see in regular (read: American) type of animation.
