A smart, original, and finely crafted thriller that is ultimately underwhelming. Strong, understated performances and a tense atmosphere, though it was marred by the slow pacing – with many long take of long silences – it seemed to by trying to hold the tension longer than it could really sustain. Much has been made of the “shocking and disturbing” ending, but I actually found it incredibly uninspired and unsatisfying. An interesting film, but overall a disappointment.
