this isn not a good movie and star usually good actor like hill harper and taryn manning and michelle rodriguez that do not seem to focus this time maybe they fight it would be like a vacation shoot the movie . two people have big role than them and i do not know their name nor would i want to consider how awful they be . the movie be not scary and while be trap by devious dog from hell they manage to have a good time drinking and stuff . not much more to say really and i guess if you already be afraid of dog like some people be then you might get scar but otherwise and no . be a guy who have a lot of dog and i could tell that the dog be in a happy mood for most of the time and which be good for the dog but bad for the movie watcher because all the tension be throw out the window . and the end be incredibly bad a well and because well i would not spoil it but the end be not satisfy .
