Excellent film, some quibbles

Rating: Null/10 (8 January 2015)

Understanding that this film is primarily about Turing's time at Bletchley, it leaves out the other important contributions that Turing made to the Ace and Manchester computer projects before his death.
First off, Benedict Cumberbatch delivers an outstanding performance, albeit one that implies Turing was a high-functioning autistic and something of a one-trick pony. Those aside, there are various liberties taken by the filmmakers that place Turing's accomplishment ahead of history.
The machine that Turing developed was actually called the "Bombe" taking that name from earlier work in Poland which had deciphered German communications in 1932. Hampering the work at Bletchley was the fact that the Nazis had added an additional wheel to the original Enigma and assigned differing daily settings for various military branches.
It was Gordon Welchman who was credited with improvements that made Turing's design practical.
The romantic interest Joan Clarke was indeed recruited to Bletchley, but not by the method depicted. It was actually by the aforementioned (and ignored in the film) Gordon Welchman.
Whether Turing truly confided his secret designs with her is questionable if Turing's loyalty as depicted is to be believed. Many former workers at Bletchley have come forward in recent years to admit that they had no idea whatsoever of the overall project for which they had put in their efforts, even after decades.
The German "mistake" transmission did not lead to solving the Enigma, which had already been cracked, but actually to solving an even more advanced German cipher then being used known as Lorenz and nicknamed "Tunny." The theoretical work on Tunny was made by Bill Tutte and was later transferred to Bletchley. It was this work that most directly assisted Allied victory.
Finally an even more advanced machine known as Colossus was designed at the Post Office Reasearch Center in London. This was the first machine to decrypt a transmission directly (which had been recorded on a paper tape reel), rather than just to determine the key to be used against decrypting messages by hand.
Lastly, even Turing's deliberate suicide is questioned, being that he had actually been discontinued from hormone treatments more than a year before his death and may not have been as despondent as the filmmakers present.
