Well, I have tickets to go see the movie, but it won't be playing for a while, so I figured I'd give you little fun facts about the characters while I wait. They might be considered spoilers for the movie (it depends on what your definition of spoiler is),or they might not even be mentioned in the movie, so I'll just stick it under a spoiler tag just in case.
Soren has starsight (he sometimes dreams about things that will happen in the future).
Twilight sometimes sings battle songs during battle to make his enemies go yeep (their wings lock and they can't fly).
Nyra was hatched under an eclipse. There is an owl prophecy, legend, whatever you want to call it that makes it so that an owl will either do great good or great evil. It is also the reason she is white.
Outlissa is related to Stix Emerella, the renowned weathertrix of the last century.
Twilight's mother is actually a renowned poet
Yeah, that's all I have for now.Edit:
I went to go see the movie now, but it would take too long to review in this post. I guess I'll just sum it up in ten words: Whoever worked on this should do The Last Airbender 2.
Anyways, I watched the movie and realized that the only real spoiler was the one about Kludd, so I just put that one under a spoiler tag and left the others.
