while this movie boast quite a string of genuinely scary moment and it be essentially a collage of already successfully test horror plot . agoraphobic heroine and serial killer and ghost of serial killer and etc . it even have the obligatory paranormal investigator . nothing stand out a truly original . honestly and i have see bad act in support role but not very often . the lead role be execute quite well . in fact and i would not be surprise to see this young lady do well in future movie . again and it be quite scary at time and i suppose that the point and eh . also and the music be pretty good . anyway and if you be a horror movie buff and then watch it just because .
