Watching this on a big screen one realizes how much effort must go into the "Life on Earth" and subsequent TV documentaries. This looks really mundane and unimpressive, even with the benefits of the cinematic experience. Maybe my expectations were too high, but if it had run another 30 min. I would have been asleep before the credits. There is about 15 min. of impressive footage of sharks and dugongs, but most of the rest is really repetitive and no better than a hundred other underwater wildlife documentaries.
