A very well made film.

Rating: 8/10 (29 March 2015)

This movie is beautifully filmed, the production and acting is quite superb, however to keep things in a historical perspective I would advise everyone to also get a copy of the BBC documentary series "The Secret War" made in 1977 and watch episode 6 which Focuses specifically on the cracking of the "ultra" code, featuring interviews with the people who were actually there at Bletchley Park and elsewhere. The movie tends to give the impression, rather misleadingly, that the effort to decode the Enigma messages was done exclusively by a small group of technicians - whereas in fact it involved a vast, dedicated team of ordinary people who should also be acknowledged for their contribution.
