Summary: Watch the TV show, dodge the movie.
I expect a lot from Mr. Shyamalan. This time, he failed to deliver. While he stuck to the story, he removed most of the best aspects of the characters. In the show, Sokka and Irho are mostly used for comic relief. With the removal of the comedy, they come off more like 3rd wheels. For Peet’s sake, we never see Sokka eat! Irho never even has a cup of TEA! Also, there is way too much angst. Zuko is supposed to be all angsty, but Sokka and Ang? WTF?! Oh, and while he stuck with the story, sometimes he would just chuck in elements without any explanation, or rush through things so fast that there was no way anyone who hasn’t seen the show would ever get pulled in. Thankfully, since I had the kids there, I was able to feed of their love of the story and enjoyed myself. But I will never forgive Shyamalan for not using the statues in the air temple to tie in his past lives.
