First of all, I am a great fan of the series, and I just came here to thank
Lokhopkuen for providing the the expert Martial Art information and choreography to make one of the best animated shows out there. Seriously, you can feel the power behind the moves. They feel real, something the live-action seriously lacked.
Anyway, Lokhopkuen, you're awesome, rock on.
PS: I've heard rumors about a new series being under production, by the title of Avatar: Legend Of Korra. You wouldn't know anything about that by any chance?
