Legend of Korra; Book two trailer

[Lumenskir]

Uh, you can grind my post down to the finest powder and sift it with the finest sieve and you won't find a single mention of "evil", although Unalok was aware that Vata utilized the Sith Smorgasbord of hate, fear, anger, etc. so it seems like the 10,000 years of Darkness would have been slightly less than fun for all involved.

Also, I can kinda see your point vis a vis the spirits, but I don't think we've ever gotten any indication the Avatar was responsible for ensuring the division of people's. like, it seems much more de jure rather than de facto separation, and Wan seemed to die trying to make people stop fighting after they had started to mingle, not battling them back to their respective corners.

Also also, after watching Wan's episode again, I think an entire season of him is unnecessary. The beauty of that story is its simplicity and legend building, no need to muddy that up with needless detail. However, can you imagine what it must have been like for the second Avatar, suddenly being thrust into this war torn world saving role with none of the infrastructure that Aang or Korra had for training and such, with only one past life to make sense of it all? That'd be something to watch.

Basically, bring on Avatar: The First Airbender.
