Slow & steady pacing builds & builds the individual tensions, with a suspense which is signifying something - we know something is going to happen, but from where & by whom? Hypnotic, worrisome, brooding, until the end where everything happens. Some exquisite psychological camera work, one of the final shots is as thoughtful as one of the final shots in The Passenger (Antonioni). Don't watch this unless you're prepared to be hypnotized - when you snap out of it, something will be shaken, After all, every frame is a ... gamble.
