FredM’s review published on Letterboxd:
The plot, about German/American intelligence regarding muslim terrorism, moves along at a modest pace, like a slowly rippling stream, not meandering, but straightforward. It is not too slow to make it uninteresting, it's just OK. It gives rest, together with the classical camera work from Corbijn, who sometimes lets his photographer side talk, like in the terrific first images from Hamburg's port.
Although equipped with a decent cast, it's almost a one man show. Hoffman is impressive as our protagonist: flawlessly delivering his German accent, he treads through the movie, somber, heavy on drinking and smoking, only seldom with a lost smile on his tormented face. He completely puts the other characters in his shadow, acting as a testament of his acting capabilities in his final role, and this alone makes this movie worth watching.
