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.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

Blistering performances.
