it's... a movie.
the three crew members added NOTHING to the plot and theme. you could remove them and the show won't barely make a difference. coconut warrior had more character than these three combined.
i also hate the fact that the movie revolved around reconnecting the other tribes but we only came in contact to them in the last 10 minutes of the movie. they barely had any screentime.
great animation though, music is good but it's really a let down from the first movie.
