very good except for the end which be a huge disappointment . the script be very good a be the acting . the visuals be often very grainy but this in a way add to the film a the snowy feature be in good place that help create a mood towards the film . this affect be ruin by the extremely unbelievable end . i be go to give this film an 8 out of ten but the end knock it down a point to 7 because it seem to depart radically from the first 75 minute of the movie and seem quite force at the end to make the film maker look clever . this movie though be much good than film with quite a lot large budget and seem to be film like a home movie with some extra equipment . not much in the way of special effect a these go but for suspense it be very good .
