Korra is different than Aang. You shouldn't compare them so much. Bc in the end Aang might have saved the world, he still ran away from being the Avatar at first.
Korra does it the other way around and is just very confident.
I did find myself amused a lot in Korra and the new Iroh is as amazeballs als the old one, although the old one is a real badass. Plus I wanna see Zuko bc he's still alive in this oneeee.
