Whilst I did enjoy this telling of the wartime efforts of the British code-breakers at Bletchley Park, I think I prefer Sir Derek Jacobi's 1996 interpretation of the achievements of Alan Turing, the brilliant mathematician who led a team of enigmatic individuals who broke the Nazi "Enigma" code. Benedict Cumberbatch is really just reprising his BBC "Sherlock" characterisation - even down to the pensive hand gestures. The story is told from quite an interesting retrospection after the pretty unlikeable Turing has been apprehended by the police for what I suppose we'd call "lewd behaviour" nowadays and is being questioned by Rory Kinnear ("Detective Nock"). Indeed, I found all the characterisations to be a bit shallow - Charles Dance, Keira Knightley and Matthew Goode just lacked oomph, I thought. Fascinating story , though - beautifully well presented.
