A subject quite intriguing. A father who lost his two children playing a game that her wife had forbidden: who goes down faster from the seventh floor where they lived. Him by the elevator. Them down the stairs. However, when he reach the ground their children are not there. Suddenly commonplaces became unknown, mysterious. The performance of Ricardo Darin, great in films like Nine Queens and The Secret in Their Eyes, this time is not convincing and does not achieve the level of desperation that reaches for example Hugh Jackman, also as a father of a kidnapped girl in Prisoners, which compels him to cross the border of what is political correctness. Nor Belén Rueda reaches the level shown in The Orphanage where she also gives life to a mother whose son disappears in her own home. The end is resolved too quickly and with serious gaps in the plot (for example, how did her wife know exactly when will they play that game? It meant that someone had to be perennially waiting behind the door to catch the children? ). Anyway, absolutely forgettable film.
