Does anyone else think that Avatar: the last airbender had a sucky ending.?

He ended up not killing the firelord (which was his destiny), this dumb*** giant island turtle thing makes a duecexmocina ( a plot device where the main character is too much of a wimp t finish the job and a god like figure saves the day, I don't think I spelled it right, but I don't give a ****). I M nights shamallons( don't know if that's spelled right either) new movie coming out, I know NORMALLY he should stick to the story but not in this case. I. hope it does not suck like some other nickolodean movies(Barnyard).
