I like this movie because it's clear finishing and little thriller...I liked it I have so many questions in this... 1.because in that town only 2 people are living grandma and grandpa... 2.how cops came suddenly. 3.when they started to kill. 4.if they like to kill ,why they liveed dog. But over all I like and can I tell me what will happend end...bye.
