Personally, I had to stop watching after a few episodes. The writing is just awful.
It's a lot of telling, not showing. And because of the poor writing, the actors suffer. There's not many good ways to deliver poorly written lines.
The changes they made might be logical, but the execution was poor. At least in the episodes I watched, it's like every character has to say exactly what they are feeling, and they do the whole "so what's the plan again" trope to remind the audience of what's going on way too often.
Sokka's character arc in season 1 was kinda botched... He was misogynistic in the original on purpose... And then got his ass absolutely handed to him by the Kyoshi warriors and it was a good moment. In this one they seemed afraid to hit the misogyny, so the moment was kinda lost, and the character development was flat.
There's just a lot is missteps, in my opinion, but the source is the writing. I don't think the acting is good, but it's because of the writing, not the actors.
Technically... But there's also a lot of waste from the 500 pack that people throw out half of. It likely evens out.
