The amount of tension this film creates despite the outcome being known is incredible. It doesn't have the same awards tier performances, cinematography, or writing of a lot of its WWII contemporaries but it's just so relentlessly compelling. John Ottman's editing is so rip roaringly good that it justifies his Bohemian Rhapsody Oscar. Every part of the film just works. The final moments in particular are very effective.
A random note but I was so impressed with Thomas Kretschmann's performance despite being in a minor role. One of those bit parts that just draws all your attention anytime he's on screen. A terrific ensemble all around though. Wilkinson, Berkel, and Cruise are really great.
Also fun to note that like half the cast of Pirates of the Caribbean is in this. It's always interesting to see hints of what movies directors are a fan of. Like George Lucas with The Wire/Red Tails.
