Something I find interesting but also kind of devastating about ATLA is how you can't ignore the characters mortality,,,
Like with most stories after they end you might get an epilogue or something and you could make an educated guess how these characters lives continue but for the most part these characters are frozen in time right where you left them, not growing or aging or changing.
But with ATLA its very straightforward. These characters will live their lives, some short, some long, and then they will die, and their children will die, and their children, etc. Until these characters we know so well are just footnotes in history.
The Avatar cycle will continue and the wheels of time will keep turning, leaving that little boy in the iceberg further and further behind.
