The term "six sensed" of course came from him =P He'll never top his first movie.
To me, his directing and vision is good, its just that his writing could be better. The Last Airbender is adapted from the cartoon, so he didn't really have to write anything "new" or put a super twist or anything. I'm fine with that. So far, they're caught the atmosphere of the show nicely, so he's doing a good job for now.
I'm just getting through book 2. Toph is badass, i wanna see how they do her in the movie as well. I really hope they get Sokka right as well. He's one funny mofo. The fight scenes should be dope too. There's always an epic battle for each episode. I wonder how much they're gonna skip..
