Very strong film. I just viewed it at the Sundance Film Fest. Top-notch cast, especially Peter Mullan as the Captain. His voice is like a limestone quarry. Great cinematography (and in the tight quarters of a cargo ship) executed by a crew that comes from documentaries. It is the director's debut fiction feature. Apparently all of his previous work has been in the documentary genre. I say a very good first outing.
Others felt it dragged at times, but I disagree. Very well-paced. It begins as a young man's desperate journey home to Europe and becomes a study of a depraved Captain. The subtext is a comment on government's tendency to outsource dirty work (in this case dealing with stowaways).
