That's really a shame. I really wanted to see what happened to Azula. I mean, she ended up having a comlete mental breakdown and having pretty much every illusion and misconception she clung to shattered before her eyes. I thought it might've been interesting to see how she lived the rest of her life from there. I mean, she was only like, 15 years old by the end of the series, so, it seemed like she could've easily changed. Plus, I don't think we ever really figured out what happened to her mother (unless we had some kind of animated movie about that).
