And it will fail, there is simply no point in redoing it untless they get a 100 episode order and can make all 100 episodes before someone fucks it over. That way there wouldn't be 2 seasons of build up to Shadow War and a season of the war because they have to shove all of it in season 4.
And even is the new evil. Everyone knows that, it's like "ast" is the new ask.
