Spoiler: The Nazis lost, but MI6 was almost as bad.

Rating: 6/10 (28 October 2016)

Cheesy and inaccurate, but dramatic enough. The very fictionalized story of the man who paved the way for computers, if the film's end titles are to be believed. The film is well paced; there's plenty of suspense, incident and emotional turmoil. On the other hand, historical accuracy goes out of the window, if that's a problem for you when handing over your spondulicks.
The inaccuracy that bothers me is the drama-class portrayal of emotional turmoil, the tearful confessions and crises, the repetition of encouraging catchphrases, and the billboard-sized depiction of what we have to assume is Turing's Asperger's syndrome. It's difficult to distinguish between Turing's struggle with having no friends, illegal sexuality (in the 40's) and his struggle to build an Enigma decoder, which makes him a joyless hero. And in the end, the government stitches him up royally - if only he'd known.
What with the school bullying flashbacks, Benedict Cumberbatch has a tough time of it, and Turing's only happy moment seems to have been in finally getting 'Christopher', his computer, to work. I'm not asking for John Gregson or Kenneth More but it's all a bit wimpy and weepy. Gays, huh? What can you do? (Ironic).
There's a lot of exposition of the fundamental problem of daily trying to find one out of 159,000,000,000,000 Enigma setting variations within 18 hours, which it's essential to appreciate to get the whole maguffin of the film, but this is well done, and on the whole the film is immersive and atmospheric.
More exciting than, but easily as cheesy as you'd expect.
