I thoroughly enjoyed this film. Some aspects of the way the film portrayed Intel tradecraft was farfetched, but films rarely, if ever, get this information 100% correct. The acting was very good. Cumberbatch, of course, is always excellent, and I thought Ninidze was very good as Penkovsky. The story is compelling, and the fact that the individuals and the events involved were tied to the Cuban Missile Crisis makes the story and film extra engaging.
