***1/2

Rating: 9/10 (11 April 2015)

The film certainly shows a negative view of British attitude towards homosexuality in the 1950s. Once you were found out, you were literally blacklisted, shunned and imprisoned.
The film deals with the math professor who worked for the government during the war and brilliantly helped to decode a Nazi Enigma Code that would allow for the allies to react before a Nazi attack.
Benedict Cumberbatch is quite good as the professor. He is essentially afraid of life and that's why he is unable to get along at first with his assistants. Of course, he is also trying to hide his sexual preference. His homosexual performance reminded me of David Niven's Oscar winning performance as a homosexual fearing life as well.
