It succeeds in setting a creepy atmosphere, and it has an interesting underlying message (such as the common disregard of the older generations).

Nonetheless, it suffers from some relevant miscasting as well as not having a clear focus on what it wants to tell leading up to an absurd ending.

Through its great make-up and fairly accomplished sense of eeriness, this movie manages to unsettle the audience member.

Unfortunately, its weak acting and story, being way better when it focuses in criticising the current needs that teenagers have to follow silly trends in exchange of virality and attention rather than the main plot of the family drama, keep this film from getting to the next level.

Exceptional photography of the Navarran Pyrenees.

The great locations, score and gut-wrenching sound design make of this a great epic.

It also enjoys of quite good SFX.

The story is overall good, especially when it focuses more on its fantastic side.
