this movie be a disaster from begin to end and i justify my summary because even though it be suppose to be a terror movie there be not terror anywhere . the idea that normal look dog could ever be scary enough just by show their teeth be something that beggar belief . even if a genetic experiment be do on the dog the movie be not scary at any point and look ridiculous . but there be something far bad and more sinister in this movie . we know they be good friend but it happen that once one of them fall victim to the dog nobody really seem to care and they be leave to their own luck . for instance and the black guy once he be bite by two dog in the cellar they do not seem even to try to rescue him from the dog they shut the door and let the dog finish him off or the guy they find in the wood wound be leave to be eat by the dog . this film be not believable at all and have many flaw . why doesn not anybody grab a kitchen knife . i will not waste any more time on this review and i will just sum it up . the plot be stupid and the idea ridiculous and not scary at all and full of flaw and discontinuity and badly write and think out . my vote have to be negative .
