I have actually (partially) seen Korra, but I didn’t remember that it also went under the name “Last Airbender”.

I thought that specifically referred to Aang’s story.

New Avatar: Last Airbender animated series in the works.

What’s wrong with the old one that there is need for a new one?

Edit: It seems I got confused by the fact that the new series is also called “Last Airbender”, which I thought was specifically referring to Aang’s story.

I am aware of the legend of Korra.
I wasn’t aware that other stories in the Avatar universe still went under the name “Last Airbender”.

Thanks for the explanations.
