MY FAVORITE PART OF THIS MOVIE.
Totally in-character Batman and Hawkeye crossover interaction, btw
The Beauty of the Last Agni Kai
The final showdown between Zuko and Azula remains one of the most beautiful scenes in Avatar: The Last Airbender and maybe even the follow up series The Legend of Korra.
I just love how the colours of their destructive firebending clash against one another and spiral across the air.
