It was a good movie, with good story , good acting, and good effects, its based on mysterious man eating fish, which was thought to be vanished from the face of earth 2million years ago, but its back, in the lake town where thousands of high school kids were enjoying their summer.
Story revolves around the sheriff of  that town, her older son and two other younger children. 
Its a good movie to watch, but not recommended to everyone, some may find it boring.
