This is the nitpickiest of nitpicks, but it usually doesn't bode well for a show / movie when the very first line (spoken or text) makes me laugh in a way the director obviously didn't intend (example: The Rise's of Skywalker's 'THE DEAD SPEAK!'). In this case, I had a pretty good chuckle over the very first subtitle 'CAPITAL CITY.' "Ooh, Captial City! The Windy Apple!"
Also, it was really off-putting how all the airbenders were oohing and aweing over Aang doing some very basic airbender freefalling.
Simple questions deserve long-winded answers that no one will bother to read.
