When the "best" lista goes on YouTube I'll subir it. I did enjoy "the boiling rock" and "water bending masters" but to each their own.
Personally I think Tales of Ba Sing Se, Avatar Day, and Ember Island Players should be here instead of The Painted Lady and Water Bending Masters. I'm not sure about my list but I know that The Ember Island Players, Avatar Day, Tales of Ba Sing Se, and The Great Divide are among my top 5 least favorite episodes.
^ actually tales of ba sing se is one of my favorites. It had the great moment between Toph and Katara bonding and also Iroh mourning over his son was a well written heart breaking scene. I guess everyone has different tastes.
