The problem with people like Turing, Einstein etc. is that nobody understands them nor the way they think (or thought). Trying to do films about them is guessing. In general, films about people this clever are crap because nobody knows what they really are.
As an aside - one thing I never read about is that not only did Turning have to crack the code, but it was all in German (and he is English) - that seems to be not recorded anywhere. So he was a not a genius, but a brilliant genius.
