I have now finished watching the entire show. And I have spent pretty much all day today since we finished the four-part finale talking about the awesome that is Avatar.

Seriously. It's like, we'll be out at dinner, and the conversation is about how brilliant the structure is and how tightly plotted things were. On the drive back, we're talking about the way the structure maps to a really good RPG campaign, and how the GM statted out stuff like the metal-bending upgrade, and what you can tell about the players by how their characters act... And I spent about half an hour after the finale just walking nervously in circles, trying to burn off the tension acrued through Massive Awesomeness.

Damn, but that's a good show.
