First off, Campanella works with flawless effort all of the technical aspects of the film. It even starts with a double exposure effect, mixed with some sad shots of a beautiful Buenos Aires that hints the spectacle ahead of us. One shot especially, from a chopper in a soccer field edited with a crane shot is breathtaking. Nothing to envy from Hollywood upper class.
But the main strength of the movie comes from the powerful narrative dominion Director Campanella has over characters, spaces and silences. Many moments are coldly tense, scary and very, very intense. This crossover from genres by Campanella couldn't have been better. Crime stories often fall in common places, this one relies on the fragile psychological state of the audience to draw all of it's intense dialog, acting and scenes.
I cannot stop recommending it, Argentina can open it's market with movies such as this. It has many, many memorable moments, it interwines comedy perfectly and it is doubtful you will instantly forget it, as it is so well constructed. See it if you can!
