OK, that was the reason to watch, now for the downside. The narration is downright dull. Sure, it has the starpower of Johnny Depp and Kate Winslet, lending their voices to the project, but it takes more than recognizable voices to make it interesting. Johnny Depp, in particular, sounds like he is bored and on the verge of falling asleep. They just sounded uninterested in what they were reading, and if you factor that in with the less than hard hitting information, it adds up to a less than stellar presentation.

None of the information they relayed is all that enlightening, but then I have a feeling that this was made more for the spectacle of the gigantic screen and the visual beauty than it was for the educational, more documentary-like narration. Perhaps I have been a bit spoiled by the Planet Earth series on The Discovery Channel.

The film is short, clocking in at 41 minutes in length. When you cut off the IMAX logos and opening/closing credits, you can knock off another 4 or 5 minutes. So, you can get a lot of beauty without having to expend a lot of time doing it.

The DVD looks great, the colors are all bright, crisp and well defined. It really is a joy to look at. The disk gives you the option of viewing in anamorphically enhanced widescreen or full frame presentations. Neither one is quite correct, although full frame is closer to preserving the original aspect ration. The IMAX ratio is, I believe, 1.44:1, so the 1.33:1 of full frame is the closest to seeing it as it should be. The audio is good as well, allowing you to clearly hear the underwater movements and Danny Elfman's score.

Bottom line: This is definitely worth a rental, the footage is beautiful, and you will get to see a world into which we do not often look. The creatures captured on film are truly amazing and makes up for the lackluster narration.

Mildly Recommended.
