But the movie is a dramatization, not a documentary. Because of that, it got the general, non-CS-major public to care about Alan Turing. I'd say that's a pretty decent accomplishment.
I actually had a conversation with my mom about Alan Turing after she saw the movie. That's saying something. She still needs help browsing the web beyond AOL. She thought computers were "unhealthy" and borderline "dangerous" until very recently. I'm pretty sure she thinks her router contains the entire Internet on it. These are the kinds of people who need to be exposed to Turing, and "Imitation Game" breaks through to them. Great. I'll take that as a net-positive.
Imagine if they told the story of the Normandy invasion as being a squad of GIs pulling one over on mean old man Eisenhower, saving the day by inventing the flat-bottom motorized landing craft.
That said, the small amount of stuff set in the future about Turing's persecution was well done.
* They presented Turing's characacter as the generic caricature of the pedantic genius, kind of like The Big Bang Theory's Sheldon. Other reports I read on Turing's personality didn't match that at all.
* Holywood seems adamant to have a romantic man-and-woman relationship going along with the story, even if it had to be a platonic one since the lead character is famously gay.
I don't know though. I've never seen it. There's a whole section on Wikipedia if you care.
