I was totally surprised at how great this film.You could feel your paranoia rise as the film went on and as you gradually learned the details of the real situation.

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

There is definitely an excellent idea hidden in the background of the film. Unfortunately, it's difficult to find it.
