“Sam’s Lake” (*1/2 out of four) was an enervated horror thriller about a young girl (Fay Masterson) who takes a group of her friends (Sandrine Holt, William Gregory Lee, and others) to the title lake where they are confronted by an ancient and evil force that threatens to kill them all one by one. Not all that different, if you think about it, from “Friday The 13th” which was a horror movie done with style and craft which this utterly lacks. This one is all washed up long before its predictable climax.
