You did not learn much about life and work in the movie made from Sebastian Junger's The Perfect Storm. Movies can indicate content, action, but cannnot explain it.
I am re-reading the book. Read it if you have not. It is not Moby Dick (no transcendent component and no poetry), but the comparison has to do with the amount of information (oceanography, meteorology, technology, sociological, and the fishing industry) that Junger packed into this story. Not to mention that he is a compelling writer. Snappy, compact prose.
The guy deserves however many millions he made from the book. Sad to say, Melville didn't make a penny from Moby Dick.
