i do not watch very many horror movie and but one night i sit down and watch this with my cousin . now and be teenager and so we tend to make fun of a lot of thing and but honestly and the acting here really wasn not very good and especially at the beginning . one line that stand out be when scarlett say to jill and tiffany and this be so . high school . while the next scene show jill walk past a sign with their high school name on it . many part at the beginning remind me of a corny and badly write and badly act lizzie mcguire episode . however and a the story progress and and the cast move on to just about only jill most of the time and i be able to appreciate the movie more . camilla belle do really well in this movie and and i think that the other actor and actress ruin the movie for her . and i must admit and this be one of the scary movie i have ever see . well and no and there weren not big monster and white face appear in dark corner and possessed doll and but the thing that make this movie scary than one contain those thing be that it really could happen . and this movie really remind me of what really be scary . we all know be not likely to stumble upon the living dead any time in our life and but the idea of have a murderer inside the house youre babysitting at could really happen . the only flaw with this movie be that it one of the most cliché movie i have ever see . it have everything in it that any horror movie have ever have turn the key and the car start and shadow in the corner and turn the corner of the stair with suspense and turn around and see a dead body and end a fatal scene quickly with wake up from a dream and etc . at the suspenseful scene and it be very predictable and but overall and i would give it a positive . it definitely worth see . by the way and this be my first review and so i do not know if any of those thing be spoiler . but just to be safe .
