I literally can not understand the very negative reviews people are giving. It seems that they are so accustomed to american-made superhero movies/series, that they can not watch something different or foreign. This movie has all the elements (plot, acting, atmosphere, plot twists) that render it a very enjoyable watch. Well done.

This could be a disconcerting film to some especially those who want a clear-cut ending. Some viewers might have expected quite a different outcome.

There is no quarrel about this stance. But what the film is trying to convey is that, in real life, what seems straightforward is not necessarily so. Could it be a streak of bad luck, a string of coincidences?

It's a well-scripted film. It's engaging and the viewer is hooked to find out how it will end. It was a surprise ending but something that is totally plausible.

The main actors dish out subdued and limned performances. Macarena Achaga, Diego Peretti and Juan Mimijin deserve praise.

The film makes you think of its basic point: is perfect revenge possible? It's apropos that it makes use of Odile and Odette as a cinematic device all the more to illustrate what we take for granted: that good and evil exist in this life.

This Argentinian film is an excellent psychological thriller. I honestly didn't see the twist at the end coming. Kloster is truly an intelligent and evil m-o-f-o. I also like that the film didn't end with a happy ending like most American films do. You won't see police lights or hear police sirens when the end credits scroll on the screen. I always feel that happy endings in thrillers and horror films undermine the film. But I can bet many other Americans will be bothered by this since it's so customary to have happy endings in Hollywood films. The screenplay is intelligent written. The actors did a superb job. As another reviewer mentioned, the actor whose name is Diego Peretti does have a resemblance to and similar acting style of Al Pacino. Al Pacino in The Devil's Advocate (1997) comes to mind when I think about Peretti. That's not a bad thing! I'm surprised this film is not rated higher.
