Informative and so interesting.

Rating: 9/10 (7 October 2015)

For me, the best scene, and deserving of a special clip on Youtube maybe, is when they are at the pub, and Helen tells about her relationship with an unknown German.
We see, and can almost hear, Turing thinking and realising that this is how he can beat the Enigma. Helen (Tuppence Middleton) (sic!!) is so good, and this is the point after which everything is possible. The worst scene is the attempt to show the convoy destruction. The CGI is amateurish, hopeless!
The basic plot is well known now, about how the whole team at Bletchley managed to beat the German Enigma code machine. The story develops well and the acting is superb throughout.
One tiny grizzle, is that we are not shown what Joan (Keira Knightley) actually does.
