Having watched the film, and in respect to most users' comments I will try and be as easy on it as possible. The idea around which the movie's filmed, is interesting. Yet not overly original. Manchurian candidate was more or less of the same idea, with some better acting to it I might add. Nonetheless, it's always an interesting idea. I did feel a slight bonding to the characters, but not overly so. Yet for a movie where the characters hardly take the time to speak to one another other than grunt, that is an achievement. And has a lot to do with their gestures, and facial expressions. Solid 'silent' acting by the two stars, the villains of the film were kind of 'fakish' to my eyes. But the married couple seemed bond well together after a rusty start. However, the 'scary' part I must disagree with. I wasn't frightened during any of the film's moments. And I may be a hardcore thriller/horror movie fan, but I do remain jumpy or frightened if something is there to actually frighten me. This movie was more so like a...film in which you knew there'd be a twist in the plot at the movie's end, and just waited to see if your guess was right. Unfortunately for me, and the friend who watched it with me, we both were more or less right over both the twist and its nature. Not recommended for watching, unless you really want to kill an hour or two watching a film. On the bright side. It's not really that bad, it's just overly mediocre. There's many better films out there. And twice as many worse.
