My big brother was annoyed that all the Fire Nation people are indians in this movie---not that he's racist, it's just he feels like the CULTURE of the people should match. Like he thought that the Fire Nation weren't all barbarians or whatever, and especially with the honor thing, they were more like Japanese.
Oh and I am disappointed with the movie stills how Zuko doesn't appear to have "the scar." Like what happened to that big, red, fire-shaped burn covering a third of his face? I MIGHT have spotted the scar, but it's so small, only slightly red, under his eye, and it's just pathetic compared to the damage that was actually wreaked in the original story.
Betcha my brother and I are still gonna go to the movie though. XD
