The set-up for this film may have been the most captivating build I have seen in the past several years. By the half-hour mark, I was completely invested in the characters, my emotions had been stirred by the antagonists, and the suspense and tension had already been set. As the film continued, however, the survival struggle in the woods became a test in tedium, with an over-extended game of cat and mouse played out between a resourceful woman and a group of teens that are pushed past the point of super-villainy in their torturous terror. The leads both earn a degree of empathy with the audience, but that link is stretched thinner and thinner as the plot continues. Ive focused on the negative here, but only because the film was composed so well at the beginning that it had the potential to be one of the best of 2008, only to drop off into an above average Survival horror. The film is shot beautifully, takes place in a hopeless forest setting, and offers very good acting for the most part. There are just moments where the filmmakers pushed the envelope too far and immediately destroyed the illusion of suspended disbelief. For a sleek Survival flick in the vein of The Strangers or Them, Id recommend checking this one out. It is still a very good film, though not without its flaws.
