Voxitype Good films always raise compelling questions, whether the format is fiction or documentary fact.

Sarita Rafferty There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.

romanorum1 The beginning of this documentary is devoid of credits. We see dolphins swimming and leaping in the open water and sea birds diving directly into the ocean to snatch a fish. The narrator (Pierce Brosnan) says, "This is a world of constant jeopardy, an endless cycle of birth, death, and renewal." Powerful waves crash into the rocky coast, where the sea lions return to give birth, but unwary seals become prey to predators (the black and white colored killer whales) in the shallows at high tide. Then again, the whales themselves risk being stranded there.More marine life is seen before the view shifts to the coral reefs, "a narrow band of sun-fed life only found in the shallows of the tropical seas." The skeletons of coral polyps – the smallest and most fragile of organisms – form the reef. The darkness is feeding time for some; the night-feeders with built-in sensors have no need of light. Fascinating and colorful sea creatures abound further below the ocean surface, but unfortunately most are not identified. There are poisonous jellyfish and manta rays. Just before the halfway mark of the film the scene moves to the Arctic (polar bears) and also Antarctic (penguins). In the Antarctic the temperature is seventy degrees below zero (-70°F) and the winds exceed one hundred miles per hour. The penguins gather speed in the cold waters before jumping out and landing on sheet ice. Meanwhile in the far north the polar bears search for nesting seals hidden in ice caves situated just below the surface. Thirty-ton gray whales travel six thousand miles to feed in the polar seas. After six hours of jostling, killer whales separate one unfortunate gray calf from its mother and move in when it is thoroughly exhausted. From the surface of the ocean we next enter a subterranean world, the deepest underwater area on the planet and where surface light does not penetrate. Seven miles deep (the Marianas Trench), it is a mystery world of perpetual night. It is a sparsely explored netherworld of odd life forms (again unidentified). The only light emanates from the undersea creatures themselves. Light is used as a lure to attract prey or as a decoy to confuse them. Poisonous hydrogen sulfide gas and boiling water spew forth in some areas. Yet, even near those settings some life forms exist. At film's end we hear that there are only a few thousand blue whales left on earth. The blue whales are earth's largest creatures by far.The narration is limited and the orchestral music appropriate. If you like nature documentaries, you will enjoy this one, although there are several lulls.

elliott237 Reading some of the previous comments I feel that I must have been watching a different Deep Blue. Although i found some of the visuals stunning i felt that much of it was appalling. Some of the 'out of water'shots looked horrible, reminded me of watching games on a Commodore 64!!! As some others have said, much of this footage has been seen before, so i really didn't see the point of this movie. The musical score was good and it did match the footage well. If sea life is your thing, I would recommend the Blue Planet. Note of interest: did anybody else actually find some of the footage very poor. I watched on a widescreen LCD (brand new), so perhaps the poor quality arose because of the screen size.

nntinx The footage was breathtaking, especially the deep sea scenes. I've seen shows and movies on the deep sea, but this was truly something special. It was almost unbelievable that BBC could capture these creatures that looked like something out of a very vivid imagination - nothing like I would expect any life forms to resemble. I couldn't help but get irritated at the orcas in the film, though, but I guess the portrayal was fair - they are on top of the food chain, and as such, they can eat anything they want. Anyway, I rated this movie somewhat poorly because the DVD cover showed a picture with a large emperor penguin, and a little baby penguin in front of it. I LOVED March of the Penguins, and I was really excited to see another filmmaker's take on the emperor penguins, even if it was not the focus of the whole movie. Yes, there were emperor penguins, but no little penguins! The penguin scene took up less than 5 minutes of the whole movie, and I felt cheated. I felt misled by the DVD cover, and I wanted to warn other penguin lovers out there - this is really not your movie if you want to have a good deal of penguin time.

Michael DeZubiria I studied marine biology for a couple years in college, and this movie has some of the most amazing underwater footage I've ever seen. It's a fascinating journey into the ocean, particularly the parts that most of us will never see, like the arctic regions and the deepest reaches of the deep ocean. Some of the shots themselves are incredible just in the way the camera crew were able to immerse themselves in the biological communities that they were filming, especially the feeding scenes. Anyone with even a passing interest in the ocean and the mysteries of life on this planet should definitely not miss this. This movie is an explanation for why so many people believe that our planet should be called Oceanus rather than Earth.
