I've started watching the new series up to Episode 10, I must say it isn't even half bad, but you shouldn't compare it to the Old series, It even got a "Last airbender'' thing going, the theme is strong enough, I even like the animation, Instead of a huge Bulky LionO , you get a smaller younger-looking one, also the story has more going for it , it isn't just about the Sword of Omens most of the time, but also the book of Omens gets mentioned much more.
I like the series, but I miss the old villains, but on the other hand Mumra seams more active in this one.
