How others will see it. Set in Argentina and subtitled, as it is in Spanish. Otherwise, a modern film with appeal to the fan of detective stories and other tales from the street.
At first, the movie seems as if it will pass unpleasantly, with Marcos and Juan drifting from one shameless small-time grift to another. The story finally takes off when Marcos gets a tip from a counterfeiter about a wealthy collector eager to spend a fortune on a sheet of fake stamps made by said counterfeiter. The scam (whoever is to be swindled) becomes involved, with many players, each with their piece of the action.
Since it's a decent film with a good story and moderately credible characters, it has all the elements of entertainment. The only ones who won't like it are those who avoid foreign language movies as a matter of course, and moralists who would like to see con men of all kinds fed to the sharks. Come to think of it, I fall into that category.
How I felt about it. This is one of those films that wrap up with a twist that should be both enlightening and entertaining. A twist that changes the whole perspective of the movie. Once revealed, it all makes sense.
In general, I don't believe in twists. Going through my list of greatest films, there aren't many real twists. Casablanca, for example, ends with Humphrey Bogart and Claude Rains as heroes. But we expected that all along, even if Rains is corrupt and likes much younger women. Who doesn't? Just kidding.
If Rains shot Bogart instead, and Rains then had a good laugh about it with Conrad Veidt, that would be a twist. And a bogus one. And most real twists are bogus, because they usually make lies out of an important character.
And so it is here. Of course, a twist doesn't necessarily ruin a film, but it generally shades it in the wrong ways, even in earlier scenes, because the director is in on the twist. In retrospect, Valeria (Leticia Bredice) is unbearably smug about her deceit. And blank-faced Juan (Gaston Pauls) is now a mastermind who knows in advance that Marcos will do this and do that. These incredibly complex schemes only work in the movies. Mindless complications, like motorcycle thieves who toss fake rare stamps into ponds, only add to the implausibility of it all.
