Aura Garrrido as the protector mother is pretty well , she is a fine actress, as she has proved in Ministerio Del Tiempo series.Support cast is frankly good such as Aitor Luna , Sergio Calleja, Patricia Vico who is Calparsoro' wife , Alfredo Villa , Belen Cuesta and the veteran Julieta Serrano.
The fim packs an atmospheric and stirring musical score by Julio De la Rosa . And an evocative but dark cinematography by Sergi Villanova , shot on location in Madrid outside , Chamartin barrio. The Motion picture was well directed by veteran director Daniel Calparsoro, though It has some flaws and gaps . Daniel has a long career as filmmaker from his beginning with Basque films as Pasajes, Salto al vacio, A ciegas , Ausentes ; subsequently making thrillers as Asfalto , Guerreros , Invasor ,and the successful Combustion and Cien años de perdon . He also directed Tv series as Inocentes, La ira, El castigo , Apaches. Rating 6.5/10 . Decent and passable yarn as well as acceptable supernatural thriller.
