Yeah i really like that they turn those last 4 episodes in to a movie , like i said the plot is age old but the characters really breath life into it espically Zuko , he is one of the most complex characters i have seen , that's why i really liked the show , without Zuko the show would have been lame.
Anyway if you are looking for any other Anime you would like to try ask me since i spent last 2 moths of my vacation watching Animes & other Cartoon series , i feel like i am a Pro in in this department now
(i rarely used to see anime before).
