13 Tzameti is a film that, ultimately, never quite reaches the heights that it threatens to in its mysterious and impressively open-ended first half an hour or so. A young man follows instructions meant for someone else in looking for a way out of his dead-end job and to provide a better living for his poor family, and unwittingly ends up in a deadly underworld game.
It starts off Hitchcockian but ends up in Fincher/Roth territory before a lazy and contrived climax that suggests that Gela Babluani, the director, did not quite know how to finish it. If he had managed to piece together something a little meatier and we had seen the fates or possible fates of some of the other characters, especially that of the police investigator who, in the end, adds nothing to the plot, then it would have been wholly more satisfying. The film's biggest flaw though is to only follow one character in this 'game' as this takes away much of the suspense once the 'games' begin.
That said, it's still a short, sharp little thriller that, despite its two major flaws, is very well shot and acted, cleverly using black and white, and suggests that Babluani could be one to watch. Well worth 85 minutes of most people's time, I reckon.
