War is hell. That we know. But how does it sound to be trapped inside a foul sardine can, with the latest technology a 40s diesel fueled U-Boat could give you, without any specific connection to the ideologies of your country? Knowing, of course, most of your fellows sailors didn't survive in last campains?

This is on par with any great hell movie you have watched, with the added bonus of retro technology, great war-is-insane criticism, characters you will really care about, and impeccable exquisitely designed sets.
