This is a psychological thriller about a Zuckerbergesque fellow who is an amalgam of Steve Jobs, Mark Zuckerburg, Bill Gates and the Google Twins in an isolated cabin in the middle of the great vast north, though the exact nature of the place is unspecified. I'm going to attempt to avoid spoilers, but the thing is that the trailer makes a few things obvious. The protagonist is there to evaluate a girl, to determine if she is really artificially intelligent or not.
The film is thoroughly enjoyable and the acting superb. Obviously, it is a bit of a head game, and the movie is advertized as such. But it is worth it and the ending is not what you expect without losing itself in the potential complexities that they could have taken with such a film or so typical of "tent pole" movies these days. This movie is not Inversion, and that is a good thing.
I highly recommend the movie. It is worth your time if you enjoy cerebral near future sci fi with little action but great acting. The visual and sound elements of the film are also quite good. It's fun to watch, just as a thing unto itself.
