This is the Sea
It's what attracted me to the movie in the first place but it seemed the film was written around the music of The Waterboys. OTOH, the young and gorgeous Samantha Morton helped.
It seems my knowledge of Greek mythology is piss poor as I had no idea it was the basis for this film until this morning from Wiki. Pretty good even not realizing that and perhaps even better now that I do.
Can't say I learned a lot from this new doc but it's not bad.
