I'm a fan of the old series and where it felt like the old avatar just had filler the writers took action to take these episodes and make them actual plot points. Where I understand that they had to rush zuko and give him a heart early on I felt like it dived more into the character of both Zuko and Uncle Iroh and while I am sad to not hear old Uncle Iroh's voice I really appreciate the character. I think that the series has exceeded the old show in a few ways but they're both really good to watch. My only complaint is fridgeing an entire nation for a call to action.
