I LOVE EVERYTHING ABOUT IT. It’s definitely much better put together and less plotholey than the Legend of Korra, which I also adore but was annoyed with the rushed nature of the first season. The third season was probably my favorite of the bunch, and my only complaint is that it took much too long for Zuko to become one of the good guys in this season. I wanted more time with him and gaang before the fire lord had to get his butt kicked.
My forever favs are Toph, Sokka and Zuko, but mostly Toph because she is the BEST. I also really liked Zuko and Iroh’s relationship, and their reunion was the greatest. As far as ships go, I kind of like a mix of everything, canon and otherwise? I dig Toph/Sokka and was briefly sold on the idea of Katara/Zuko, but I don’t hate Katara/Aang either. LET’S JUST SHIP EVERYONE.
