This is one of those films where you cannot trust what you see. It
has a complicated narrative structure which, while using many of the
clichés of this kind of psychological horror, is stylishly realised
and quite convincing. I'll probably need another viewing to convince
myself that what I think happened is actually what did happen, but
it's a good enough film to reward a second viewing.

The photography and sound design are particularly good.

Gripping, confusing (in an intiguing way), and quite frightening.
