DONT WATCH IT. I watched the whole movie and it left me confused and asking myself why I wasted my time with it. There is so many holes in the story that you we be asking yourself wait how in the hell did that happen and then the ending will just leave you wishing you picked a different movie. Would not recommend at all. One of thw worst movie I've seen in a long time. Spoiler alert they make a point to tell you that the mother and father who own the house are the only ones with keys to the door and some how the 5 year old open the red door and unlocked the other door to let in the sick dog and get sick from it. Please someone tell me how
