AR, the previous reviewer, has in a nutshell. It's so realistic, you can almost smell the sweat. You'll always be glad you watched it.
A superbly crafted film which takes you right in to the human side of the U-boat crew. Even if they are on the 'wrong side,' you side with them, thrill with them, are terrified with them, and finally maybe even cry for them. The English language version still seems utterly authentic. If I have only given this four stars, it's because I almost never award five: 4.98!
On rewatch, it’s even more suffocating. I remembered the tension, the torpedoes, the rattle of depth charges—but I’d forgotten the stink, the boredom, the hours of sweat-soaked monotony. It’s a war film stripped of heroics, where courage looks more like endurance and fear is just part of the job.
What struck me this time was how lived-in it feels. The crew’s banter, the cramped routines, the way they joke one minute and brace for death the next—it all feels grimly authentic. The claustrophobia is relentless, but so is the humanity. Petersen isn’t out to glorify anything; he just drops you in the tin can and shuts the hatch.
I used to think it was about survival. Now it feels more like a slow, rust-covered descent into absurdity. The sea doesn’t care who’s right. And by the time you surface, if you do, you’re not sure what home even means anymore.
