Absolutely incredible.
I had basic cable as a kid and I couldn't get through the whole series episode by episode. However. I remember being awe inspired by Book 1 (Water) and loving it so I hopped on the Netflix Bandwagon and worked through the whole thing.
I am so happy I did. In fact, I'm a bit sad I finished it, as art this beautiful is rare. This show is profound, as well as very innocent in its approach to life's issues. It prompts you to look inward and teaches you indirectly about human nature, destiny, forgiveness, common mistakes we make, and many other things.
I'll say it: greatest show of all time. Thank you cast and creators. You are the grandmasters of your craft.
