absolutely nothing happen in this sloooow and annoying and thrill less thriller direct by amenabar usual collaborator mateo gil . the film and which in some way deal with the effect of boredom and the quest for thrill and actually delivers none and and seem like an exercise in boredom . the only mildly suspenseful moment be the movie climax and which take about 30 second of the whole agonizing 100 plus minute and and be resolve too simply . the plot lack sophistication or credibility and and while the idea be original and the way the story unfolds be arbitrary and every plot device or twist be a result of outside interference ( deus ex machina ) . the hero be always passive and everything happens to him without force him to show any initiative or resourcefulness . if youre fan of the genre and watch tesis instead .
