Avatar: The Last Airbender Fan Question!!!!?

Boy did that movie suck. I'm guessing since this movie is based on book 1 the director was playing on Katara not really knowing how to water bend that well and this girl here look scared and nervous. Which is bull because even though Katara wasn't advanced in water bending she was determine and fearless. I really hated how this movie was done. Zuko didn't need fire to firebend he generated fire on his own. And Aang didn't have a blank as look on his face.
