A tense story It kept me on the edge of my seat. True, the story has a few plot holes, but the sheer tension of it, the way the director just keeps challenging the premise is simply fascinating.
José Coronado and Adriana Ozores are two of Spain's best actors (see La vida mancha and Héctor) and here they appear as a happy upper-middle class couple. Beneath it all, the truth is that all of Coronado's life is a lie. He's not an economist, never went to college or does not work in Spain's Central Bank Reserve, as everybody else believes. We get a few insights as to how he kept up appearances or manage to do it, and while not very plausible it is still somehow believable.
The inner-workings of the scam are shown intermittently, but it is credible because Coronado is a source of self-assurance and assertiveness. He not only believes in the scam, he also believes in the film premise, and therefore he carries it.
Sure, it tests belief that a wife would not know the inner workings of a marriage's finances for almost 10 years, but again, since he's supposedly a brilliant economist.
It has been said, in a nationalistic tone, that the movie is not "distinctively Spanish", as if that were a litmus test for good film. True, no castanets or odd cabbies in this one, just a taut thriller. You'll want to know how this story ends once you start watching.
