I'm new here and from watching the reruns on NickToons, I must say I'm an adict of this show. It's got lots of great action mixed with humor. And episodes like Sokka's Master, Southern Raiders, and Sozin's comet pts 3 and 4 were among my favs in book 3.
As far as the episode: Ember Island Players, I thought it was a good episode being that it recapped a lot of the previous seasons [which I haven't watched till just recently] and got me caught up the the finale and really allowed me to make sense of the entire show up to that point.
The first episodes I saw were the Boiling Rock. So yeah i started watching the show real late. Shame the show is finished. I mean there's not much more to add now that the world is at peace now, but I guess I just wished they could have some more stuff like a movie or whatever.
