Actually, I'm really kind of excited for this movie. xD Even with all the wank going on about the actors. They matched face shapes to characters well, and the whole point of acting is to be someone who you really aren't so we'll see how that all goes, I guess. I, personally, think Jesse's face matches Zuko quite well.
also, @ people who wank about not asian people getting cast, the whole point of avatar is that the different nations are basically representing different areas/continent in the actual world. not everyone has to be asian, really.
fire nation = china
water nation = arctic and antarctica
earth nation = north america & native americans
and well, air nation is kind of gone, so who knows?
...just my personal take on the movie. : D
