I just finished watching the series finale. I have to be honest, it felt a bit underwhelming to me :( So disappointed. The best part, for me, was seeing Varrick and Zhu Li get married. And the ending shot....umm...huh?
So, the greatest Earth-Bender who ever lived finally got her butt out of the swamps after all lol. I'm hoping to see a reunion between Katara, Zuko, and Toph in the future. There are still a lot of loose ends that haven't been tied together, and I hope some questions(who is Suyin's father?) are answered by the end of the series.
