Throughout practically its whole history and starting at the commencement of the XX century, getting to produce 200 films a year during the 50s, most of them distributed throughout Southamerica with highly popular impact (why that stopped is another story), the immense majority of this production was, to put it mildly, very poor and in general low brow with a handful of exceptions here and there, not enough to justify an international prestige.
This is the case no longer, for the last two or three decades, the Argentinian film industry has been producing excellent work, like the film we are considering now ("Sin retorno" -2010).
The script is very well constructed and the pacing of the story is frankly Argentinian, because although it's a thriller, it has nothing to do with an European or better yet, with a Hollywood product.
The story becomes quite suspenseful once its drama is unleashed to show us the moral and in one of the instances the physical danger of all the characters involved. The unimaginable consequences of a lie swelling up like a wild, unstoppable snowball coming down the mountain side at full speed, being impossible to imagine what tree will stop its run (the end is absolutely unexpected).
Very interesting because it makes you think if it's worthy to tell a lie when it'll get so entangled that your life will never be the same, no matter how many more years you'll get to live.
Excellent acting that grabs you from the beginning without letting go till the very end. Technically impeccable. Very-very entertaining.
