If you are expecting a neat little movie with a clear plot, that leaves you with a sense of having experienced something you can summarize easily ... you'll be sorely disappointed. This is a horror film in many senses, presented as poetry and intellectually obscure.
Its title, Leviathan, is a reference to the biblical passage that depicts man's encounter with a sea monster. Here, the monster is man, ripping life from the sea and destroying it in the harshest of ways, butchering sea creatures in such a matter-of-fact, emotionally detached way as to bring you to tears. But the way it is filmed creates a detachment of its own, sort of stifling the viewers' emotions so we can watch without turning away.
It is on its surface a commentary on the commercial fishing industry ... how we have reduced mass slaughter to an assembly-line process ... much like what the Nazis did to the Jews. When man turns against man, we are horrified. When man turns against nature ... it's just business as usual.
If there is a message to the film it's that we are the monsters on this planet.
