I am a huge fan of Moby Dick. I've taught it as a novel; I've read it several times. Its artistry is beyond measure. Herman Melville certainly knew his stuff when it came to whaling and the sea. Apparently, Melville gained his inspiration from a particular whaling voyage that produced fodder for his imagination. This film takes the fictional Melville back to the time where he heard the story of the white whale. If one looks at the book as the allegory it is, we put the stamp of whiteness and all the implications of the color (or lack of it) that it implies. This movie takes any artistry out of the story. Ahab lost his leg and pursues the elusive cetacean in the ultimate act of revenge. Here, a bunch of guys get in over their heads. They had an overzealous captain who simply was out for the commercial value of the animal. When the whale destroys the ship (they do give him supernatural powers) part of the crew is in whaleboats, trying to get someplace safe. Terrible things happen, including cannablism, and some manage to hold off their fates till they are rescued. But there is something dull about the pacing of the story. We aren't made privy to much of what goes on among them. There are the obligatory sacrifices that are not new to this genre. It's a decent movie, but a better script and some more personal depth would have helped.
