Can we start a petition to get the Avatar series picked up by Netflix after Book 4? It is very clear that they are writing Korra for an adult audience. I wonder what this world would feel like, if the writers had more freedom.

The Red Lotus would gain nothing, but Korra would lose her mentor and it would force her to step into his shoes more than she already has this season. With Book 4 coming, I can see that being very impactful from a characterization standpoint.
