There is one review here who rated this movie a 3. Apparently he can sees little value in a film with no violence and cuss words. He also states, "this film over emphasized and exaggerated the American experts' role in the actual project." With just a little research he would learn that the idea behind the project came from Drexel University environmental scientist James R. Spotila . So the reviewer who rated it 3; not much credibility. See the film. OK for kids. It leaves some unanswered questions, but is an interesting film.
