Bad Movie
Spoilers.
To begin with, the one shoot camera did not fit well in the movie. What was the point? To dark for my taste. I know that showing little or nothing (total darkness) can produce an effect of desperation, but this movie used it excessively. You do not see a thing in the hole movie, from the begining to the end, just flashes and dirty walls.
The movie plot is a copy of High Tension, uruguayan way. Scariesta part in the film, the credits, with fake photographs.
