I have been one of the voices in the Racebending debate around the new The Last Airbender, but this new teaser looks good but not great.
My first complaint is that the martial arts do not look as natural as I would like for Aang. Secondly is the voice over.
They make the movie sound like it will be a Star Wars meets Harry Potter film, and while that is a good thing to bring a broader audience to The Last Airbender, I only hope that does not mean they have rewritten the story to fit into that mold.
Other than that, it looks good. I cannot wait to see more.
