This nature film is full of information, and the wealth of knowledge being supplied in in combination with the great imagery is all that saves it.
The music is so annoyingly bad that it acts as a constant distraction, I cannot put it any other way than it sounds amateurish. The narrator sounds mediocre. He speaks clearly and annunciated, but his voice is just not interesting. When choosing a voice that your viewers must listen to for 45 minutes, you should find a great, captivating voice talent. Perhaps the enormous amount of narration required to include so much information resulted in a very long script, but that could have been dialled back with better writing, allowing for a more relaxed pace.
