Director Nacho Cerd succeeds in pushing the haunted-house movie into an abstract realm where the past and present fold into each other.

The movie sinks so deep into deathly atmosphere that there's no life to it.

Heralds the arrival of a new talent that every horror fan should keep their eyes on, if they're not covering them with their hands.

Focuses too much on delivering a creepy tone, overlooking the story, which is ultimately too convoluted to be scary.
