a film that split people in to two group indeed . first of all let look at the bad review and well to begin with there be no ghost moose . the tension and horror in this film do not look to supernatural or alien thing to scare u . their might be a hint of that but when it come down to it it about our imagination and our superstition and belief that trigger our response to situation . the exorcist have a massive audience compare to this but it be all make up hokum and mostly hysterically funny . at least the last winter try to take in to account cause and effect from a scientific point of view . it may not do it very well at time but the film have consistency . apparently most american do not even believe that global warming be happen let alone that human be contribute to it so it not surprising some of the film message be dismiss . a gas that cause hallucination and paranoia . we have make them so i be sure nature can . if you be not a gore fest carnage freak then this be a film for you .
