Everything is perfect. The humor, the characters, the animation, the story, the music, the symbolism. There's a lot of love put into this series and it shows. This is an incredible show and I will always recommend it to everyone. A lot of anime/cartoons have female characters that are useless or dansel in distress, not this show. The girls in this show are also amazing. A lot of good lessons and role models for kids. For example, there's an episode in book 2 with Toph and Katara and they go to a spa. Toph gets a makeover and a group of girls bully her because of her appearance. She bascially states that she doesn't care what people think about her and she knows who she is. This shows a great deal of confidence. Katara also sticks up for her afterwards. I think this is a great lesson for girls. I could go on and on about how amazing this series is. Just watch it for yourself. You won't regret it.
