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.

In truth, there is barely enough story here to make a film.

As somebody who had not heard any of this before, it became a curious phenomenon to sit and watch a film and slowly have the realities begin to click into place.
