I love listening to the original intro 3 times in the first episode.

I would have never known that the 4 nations lived in harmony until the fire nation attacked, or that the Avatar, master of all 4 elements was the only one who could stop them.

I also love learning that Aang wants to eat banana cakes and goof off with his friends instead of being the Avatar by him outright saying it instead of us meeting ANY of these friends in the first place.
