They didn't have much time to tell the story, some of the levity was sacrificed (unlike other adaptations which ditched ALL of it). In doing so, they lost a fair amount of character depth because it was during those "slice of life" episodes that the characters' personalities and friendships really developed. In the Netflix version, they are almost exclusively focused on the most dramatic bits, which means less lightness and more Aangst.

All that said, I still think it was a solidly executed retelling, even with the changes to the narrative. I am somewhat wary about how they'll handle Toph in season 2, as she has the most...difficult...personality and I think the likelihood of them having less of a balance between her brashness and her earnestness means that she's going to come off even more differently than the season 1 characters did from their original series incarnations, and that would be damn unfortunate.
