“The Dark Below” (* out of four) was an inept horror thriller about a young woman (Lauren Mae Shafer) who struggles for survival beneath a frozen lake while a demented serial killer (Zachary Beck) stalks her from the surface. Anyone who makes it to the end of this mess will have the real feeling of a struggle for survival. Amazingly, only 3 words are spoken in the entire film but believe me- you won’t be clamoring for anything more. You’ve got to give the filmmakers credit for attempting something this bizarre but the results are confusing, unpleasant, and unwatchable. One-time “Alien” co-star Veronica Cartwright has a head-scratching role as one of the killer’s other victims.
