The Last Airbender was a great TV show with good plot, but can we talk about that one scene in the beginning of season 2 (SPOILER WARNING) where, before he met tuff, Aang and the gang fell in the swamp and found hallucinations of the people they cared about and Aang's hallucination was Tuff. Then we get an explanation from waterbender-viney dude saying that the hallucinations are the loved ones you've lost. So for the rest of the series I expected that Tuff would die and I would cry, but she didn't
Also, at the very last episode, we never knew what happened to azula after zuko became king I was a bit sad, she was my favorite character.
Even after those complaints, still give it a 10/10
