This review may contain spoilers. I can handle the truth.
It's often hard to tell exactly where this is going and, at times, it even seems as if every seemingly supernatural moment could still be explained away. Ultimately, this is the rare film where the reveal (and it's very much not a twist*) actually pulls everything into better focus and a coherence is achieved that wasn't fully there before. Even before that, though, the astonishing skill with which each scene is built -- through sound, editing, mise en scene, performance, etc -- is something to behold.
*if there is a twist, it happens nearer the beginning of the film thab the end.
