This film is exceptionally filmed and performed. It's a necessary reminder that war is for keeps and not at all glamorous, even if the effort is a beautiful effort to save 1600 lives.
Villeneuve is one of the best directors alive. He his streak is 3 near-classics and counting. His sensibility is one of quiet observation. He allows the viewer to draw his own conclusions on what they are seeing, without pushing even subtly in any direction.
