A tantalising tale. Tightly knit and woven supremely to keep the suspense alive, this is a masterpiece. Excellent cinematography, background scores and outstanding screenplay are the 'Spine' of this movie.
What was amiss, however, was a little better acting from some characters. Especially, the character 'Blonde' seemed completely mysterious as ever at the end of the movie, and at times, bland. It's true that the director took care to expertly shed light on each character a little at a time, and never too much or too less, which kept the suspense running. This manoeuvre although, had both good and bad consequences. It kept any character from becoming less interesting, but, it also raised a lot of questions the movie didn't care enough to answer.
At the end of the movie, we know enough about some characters to determine what drove them to do what they did. Then again, some characters, we knew nothing about.
The apparent protagonist character 'Blonde' is a prime example of that. What are her capabilities? What drives her? Sadly, we only see a fraction of her potentials. Maybe it would have been wise to explore each character a little more. To let the audience know about their passions and drives.
Shot in only one room, the story is not multi-dimensional, but it will keep the audience hooked through-out it's course and keep wondering, what is the question?
All in all, a great watch and a movie worth visiting over and over again.
