Should this be an American movie I'd rate it 7: we've seen this before. Being this an Argentinean movie, and being myself Argentine, I'd like to give it a 10, since it's the kind of quality I'd been hoping -rather than expecting- for. It's superb quality is astonishing, given all the limitations imposed by the 3rd World...
I can't forget the scene when Díaz forces Silverstein's fiancé to confess -you know what I mean if you saw the movie. I think that's the key moment of the movie, not surprising maybe, yet original. That's when the real action begins.
Before watching a movie I always try to gather some previous information. Being this a mainstream, satyric, commercial one, I press "Play" and make a suspension of reality and logic, I'd say the best state of mind to enjoy movies like this. It's impossible to discuss the plausibility of the whole plot, yet it's believable in a certain way. As for me, I couldn't stop laughing at every single joke and commentary -"sos malo" ("you're mean")... put in the mouth of Díaz, the greatest one.
I'm rather tired of seeing movies "designed for" Peretti. I know he's a superb actor, but sometimes I feel his roles unfairly opaque the rest, Luis Luque's role in this case. I'm not very fond of Argentine television, so I haven't seen much work from Luque, but it's pretty obvious that he's an excellent performer. His physical role, his stares, his content attitude in this movie made me fall in love with his performance. I think his role should need some upgrading, just to let him show us how great he can be!
I don't know whether Szifrón is planning to make a sequel or not. I know he won't make it if it's to follow the rule that "second parts were never good", so if he makes it, I'll surely go see it. And I hope that, in the future, takes into account the possibility to give Peretti's counterparts the same chances to develop their roles.
Great movie, great performances, and lots of laughs!

Ever watched a movie that lost the plot? Well, this didn't even really have one to begin with.
Where to begin? The achingly tedious scenes of our heroine sitting around the house with actually no sense of menace or even foreboding created even during the apparently constant thunderstorms (that are strangely never actually heard in the house-great double glazing)? The house that is apparently only a few miles from a town yet is several hours walk away(?) or the third girl who serves no purpose to the plot except to provide a surprisingly quick gory murder just as the tedium becomes unbearable? Or even the beginning which suggests a spate of 20+ killings throughout the area even though it is apparent the killer never ventures far from the house? Or the bizarre ritual with the salt & pepper that pretty much sums up most of the films inherent lack of direction.
Add a lead actress who can't act but at least is willing to do some completely irrelevant nude shower scenes and this video is truly nasty, but not in the way you hope.
Given a following simply for being banned in the UK in the 80's (mostly because of a final surprisingly over extended murder) it offers nothing but curiosity value- and one classic 'daft' murder (don't worry-its telegraphed at least ten minutes before).
After a walk in the woods our victim comes to a rather steep upward slope which they obviously struggle up. Halfway through they see a figure at the top dressed in black and brandishing a large scythe. What do they do? Slide down and run like the rest of us? No, of course not- they struggle to the top and stand conveniently nice and upright in front of the murder weapon.
It really IS only a movie as they say..
