This is a truly terrible film with some reasonably good acting.

Rating: 1/10 (15 April 2015)

How this film ever managed to get Oscar nominated for the best adapted screenplay is beyond me. The old press adage "never let the facts get in the way of a good story" doesn't even apply here as the story, as told in the film, is the most complete and utter tosh from start to finish.
Anyone with even the most cursory knowledge of what went on at Bletchley Park and Turing's part in it should be infuriated with the raft of inaccuracies presented as fact here and the frankly ludicrous supposition that Turing would have told anything at all about his work there to a rookie detective.
Special mention should go to the scenery-chewing performance of Charles Dance as Alastair Denniston, leading his band of Military Police thugs to destroy the Bombe (hand-built by Turing on his own at Bletchley and lovingly named 'Christoper' by him, according to this film, but in reality built in Letchworth by a large team which included Gordon Welchman, Oliver Lawn and chief engineer Harold Keen and actually called Victory.) Denniston was undoubtedly somewhat antagonistic towards his motley team of code-breakers, but this portrayal - no offence to Mr. Dance - is so over the top as to be laughable. Yes, the acting is good, given the drivel that is the script, but I finished the film furious at the injustice done both to the people shown and to those shamefully airbrushed out.
As others have said, there are amazing stories to be told, both about Bletchley Park and about the life of Alan Turing and there are many excellent books, including Sinclair McKay's 'The Secret Life Of Bletchely Park', which tell a much more accurate and, in my view, engrossing tale than this appalling travesty. Do yourself a favour and read them rather than watching this steaming pile of ordure.
What finally persuaded me to write this review was overhearing a conversation in a diner in Brooklyn where someone who had just seen the film was describing it to his dining partner with these words "And this guy, this Turing, single-handedly saved the lives of millions of people despite being persecuted and blackmailed for being a fag." Way to go, film-makers.
