This great mood movie, but do not expect have many happy moments when you watch this.
This is dark horror, which gives one of greatest monsters in movies ever. Mysterious cargo, which won't do anything, it just sit there safely in corroding barrels and its presence is slowly rotting away morale and sanity of crew members, while some dutifully try to do their job to the end. Most characters are bit hollow, but if care them, you are watching wrong movie.
The soundtrack is excellent in monotonic dullness and I would love to download and play it whenever I want to sulk.
