If it hasn't been demonstrated by my cluing references, Avatar: The Last Airbender is one of my favorite shows. I think I just completed my 4th or 5th re-watch a few weeks ago. Great storyline, characters, character arcs, action scenes, visuals, and lessons. I swear it's not just for kids! I want to get my niece and nephews to watch it but they (I think both, but definitely my nephews) are maybe a little young. Anyway, this theme was born from the central element of that universe.
I've always heard that filling a grid with theme answers that are not on one straight line was more difficult. Thankfully the theme material here wasn't too dense as to compromise the fill greatly. I was able to get some nice long answers and I really like the 16-across and 3-down crossing.
