Hmm well I did watch it but it wasn't catching at any time, sadly. I only forced myself to watch just so I could say that I legit disliked it xD.
The characters are pretty much staying at the same spot, and it just became way too steampunk or smth, if you see what I mean. I don't like that kind of atmosphere, but it's just me.
I also absolutely hated the Airbender costumes they invented near the end of the show.
