Personally in the movie, the effects were decent but still a horrible movie.
REASONS WHY IT WAS HORRIBLE!
1. Sokka was pronounces Sewka and Ang Aong
2. Appa looked akward
3. firebenders could not make fire
4. Sokka did not have a uncontrolable desire for meat
5. Sokka was not sarcastic or skeptic.
6. Katara had no hair loopys!!!!
do you agree???
It wasn't really the little details that got me ("OMG their hairstyles were so not like that in the show!"). It was the big important stuff like the writing, directing, and acting (which is what usually makes a movie worth watching) that completely flopped. The dialogue was terrible and most of the acting seemed completely forced and unnatural.
That and the fact that no one in production seemed to have watched a single episode of the series. The actors didn't know how to relate to each other or even how to pronounce the names of their characters. I understand why the plot had to be so condensed, but it missed a lot of major themes from the series. It was like whoever wrote the script just read a summary of the show's plot and went from there.
I went to watch it with people who had never seen the show and even they agreed that, other than the stunts and effects, it pretty much sucked. The story wasn't well told and didn't make much sense unless you already knew what was supposed to be going on from having watched the show.
The only thing I really liked at all were the costumes and sets, which were great. But I wish they had spent a less time trying to make the movie look good and a little more trying to make it actually worth the money and time I wasted watching it.
In conclusion: I really hope the movie did badly enough money-wise that they've decided not to continue with a Book 2 movie.
Honestly, I don't think it was that bad.
Sure, I missed the loppys and the meat and the sarcasm just as much as any other fan, but if you haven't seen the show it wasn't so bad.
At first, the names, the appearances, the Indians(nothing wrong with Indians but, c'mon, M. Night Shamamalame, since when was Zuko an Indian guy?), and all of the technical stuff really bothered me, but I got over it. In the end, what really pissed me off was the poor story quality and the acting. The characters seemed forced and unnatural, the story was rushed and unnatural... It just didn't work.
Will I watch the movie again? Probably not. Will I see books 2 and 3? Yes.
