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.

While it doesn't offer any answers, it both thrills and makes you think.

It is interesting even when nothing much happens, which is for most of its 3-hour running time. Read full review

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