Despite the heavy-handed jingoism, I quite liked this one. In stark contrast to the actual human beings of, say, Das Boot, we are expected to believe that each German soldier is just another interchangeable member of the Nazi party, all working toward the same evil goals. Not exactly the most nuanced portrait of humanity.
Still, the film is not without moral commentary on this, shown in one of the most chilling scenes I've seen lately.
While it lacks humor, it packs in the pure Hitch visuals - beautiful compositions, technical constraints, a focus on key objects. And the story is otherwise compelling and keeps you guessing (although perhaps it's because you think that it can't possibly be so one-sided).
