this movie be imperfect ( it sag a bit in the third quarter and and some major factor in the plot be unexplained or confuse ) and but it be a great mix of fear and excitement . the cinematography be quite ahead of it time ( the camera rarely sit still and yet remain unobtrusive ) and the drama be milk for maximum effect ( and there be numerous sudden shock ) and and the science fiction or occult aspect of the film never overshadow the human element . two similar movie and david cronenberg scanner and the brood and have more science and be more amusingly grotesque and but the fury have a coolness and tightness to it that might just beat them both .
