Nice depiction of Wan! I loved it. When I read about how Wan became the first Avatar I liked him instantly. I mean, if Zuko is an allegory of Buddha (the prince who was brought down to earth after witnessing the hardship of the world), Wan is definitely an allegory of Prometheus, who stole the fire to help mankind. His story is fascinating! When I started researching on Book 2: Spirits, I was at first confused that the Water Tribe Civil War had nothing to do to the Anti-revolution, and at first I decided I would ignore Season 2. Everything changed when they threw in the backstory of the Avatar, and I was instantly hooked into Season 2. I hope that, after they finish with The Legend of Korra, they make a series about Wan, focusing on his struggle to pacify the world.
I believe Bryke don't have an intention of continuing with the "Avatar" series… as far as I know. I would also like t se a series focused on Wan. But to be honest, the legend of Korra has dissapointed me in varios ways, like the terrible love square they made. And I feel they kinda rushed the first season in their main plot (too much senseless Makorra/ Masami on their way). But I think they tried to mend this in season 2 with their Tnzin- Aang argument which was a very good thing to point out to the fans that want legend of korra to be just like legend of Aang. Also I wasn't very intered in watching season 2 because of season 1, and the first episodes weren't very amusing to me until Wan comes in.
