in fact and part of it i like a lot . it have some interesting twist . but it just leave me with a be there and see that feel after all of the saw movie . grant the end be different from a typical saw and but let face it . a group of guy and unknown to each other ( or so they believe ) toss together in an abandoned chemical factory . but then it lose something . there no intensity and there poor group dynamic and there no sense of urgency . some nice twist at the end and and definitely worth a watch if there nothing else on your plate and but it just leave me empty . it pass the time and but it do not satisfy .
