Loved it. Starts slowly, but keeps you interested. Like real life, it's hard to put into words without a spoiler alert, but, being a true story, leave it to your imagination. Not a great action movie with guns fights if that's what you want, just well acted suspense on the edge of your seat. The yanks come out smelling of roses, the brits not so, imo. The Russians are just Russian. I thought it was a great film.
