Entertaining film let down by over acting leads, poor grammar and political point scoring

Rating: 8/10 (23 March 2015)

Overall a really good and entertaining film. It keeps the viewer gripped pretty much all the way through. I did find that the pervading Americanisation (if that's a word) of our English language more than a tad irritating, is it ruining the English language and in due course British film-making in the process? Use of certain words, that alas seem commonplace in England in 2015, were not used (in the context portrayed in the film) in the 1940's and 50's Words such as "firing" in place of say, dismissing and "hiring" in place of recruiting are a sad reflection that British films and more pertinently, prominent British actors are either pandering to USA vocabulary or so ignorant in the use of the English language they are lazily picking up USA slang for proper English words and being allowed to utilize this lack of talent on film.
I did find that the acting, or over-acting from the two lead actors was embarrassing. The Oh so British accent of the elite class is all very well if one lives in Buckingham Palace but to imagine a perceived "ordinary" young lady (Joan Clarke) whose parents show such working class values and attitudes talking in such a manner highly ridiculous.
The two leads would be better placed in a theatre where such hammy acting and OTT British accents are more attuned with the audience.
The male lead overplayed the clichÃ©d stuttering and stammering English eccentric mathematic genius to stereotypical perfection. A perfection that unfortunately all too quickly reminded me that I was watching a theatrical performance, not for long could I be engrossed in the plot, the acting was over the top. Ironically, the usually OTT Charles Dance played a very believable character and his performance was very good.
Whilst Alan Turing's sexuality was pertinent to the story, I feel that the film-makers have placed far too much emphasis on it. This, I feel is bourne out in the words at the conclusion of the film quoting how many men have been charged with homosexual criminal activity since the 1800's seemed a cheap political shot and an effort at propaganda.
The film-makers seem to be inferring that Alan Turing ended his life because of his prosecution for homosexual activity or his forced hormone therapy treatment. This is taking a liberty and a more fitting and balanced conclusion would have been to say, "Mr Turing took his own lifeÂ…" This would leave the viewer free to follow up the demise of Alan Turing if they felt so inclined, hopefully by using more factual accounts.
