I thought it was good. Slightly hammy at parts but hey it was a kids cartoon, albeit a deep one.
There was a lesbian Omashu love story? I didn't even notice the change lol, didn't make any difference at all, wasn't in your face, doesn't matter at all to me. It's not like they were like hey Aang is super into gay orgies now, it's literally a few seconds of cave paintings, touch grass if it really matters that much to you. There were people back in the day getting upset about this, even though it's the original characters and not the excuse of "but they changed the character!"
But where is all the Appa?! Appa was one of the best parts and got very little personality or screen time
