I have to admit I didn't feel attracted either by the poster or the plot summary. Yet the experience was thrilling and full of surprises: the acting of the four protagonists is excellent and I enjoyed it all the way. Also, although the genre of psychological thriller is not my cup of tea, the director did a great job creating a disturbing atmosphere sustained by a very good script, good dialogues and deep human characters. The first work of Katz as a director is, in my opinion,a successful debut: the movie is filmed with great sensibility and the art in general is perfectly in tone with what we feel from the very beginning.
Highly recommendable, no doubt.
