Mood This is one of those films which you like for the mood, not so much the overall story. It's blue (literally and figuratively), it's always raining, and it reflects the inner turmoil of the main character, Amaia.
There are far too many stories unresolved. I was far more invested in Amaia's backstory than the killings themselves, though the ritual of the killer was fascinating. The story is placed with cultural references - from mythology to food.
But really, why was her mother so angry at her? If she was "demented," as even the doctor who treated young Amaia insisted, then why was she the only target and not her other sisters as well? Why is Flora so angry at Amaia, accusing her of abandoning their mother? Why is Ros silent? Did they not know what happened to her? Where were they in the shots where the mother was mistreating Amaia? And why couldn't the father step up and take her away from the mother, since he seemed to know she was being maltreated? I mean, the haircut alone should've alerted everyone who saw her, right?
To me, this felt a bit like Pan's Labyrinth, but on a more realistic scale, if you can call it that. It had the same feel. I did enjoy this, despite the lack of resolution on the part of the protagonist's story, which I felt was the real story in this film.
