the last airbender , the movie

i went today to the cinema to watch "the last air bender" . this movie is based in a series that i loved . the story is about a boy called Aang who is the avatar , the only person capable to control the 4 elements (water , air , earth and fire ) . his mission is to save the world from the war, started by the fire nation .in my opinion the story was wonderful and interesting , i like the visual effects and the music was great! . but i was expecting to see the whole story in 1 movie . but it is going to be divided in 3 parts . and i also would have liked it to have more jokes and a bit less drama.
