I felt silly at your Iroh thing. Two thoughts crossed my brain, the first being "What's wrong with that?" and the second being "Well, duh".

I know it's going to be a horrible travesty of a movie, but my god I'll go see it anyways, I'm sure. I'll be sure to bring tissues to weep over the M. Night bastardizations. I can hear the cries of distain from the choice of Zuko, but I will say that he's a fine actor who's fake scar isn't nearly big enough. Not to mention the copious hours put in the tanning booth apparently. The skin colors kind of flip-flopped. Can't have those main characters being colored! God forbid the villain was white like he's supposed to be.
