The clicking sound of the creature in Predator was very effective, so it was imitated in many films, some fairly decent. Likewise "Saw" has a very popular voice mask that has been used in other horror films, including this one. As a disclaimer, I was into my third "Saw" film when I stopped watching them as the franchise quickly lost its appeal to me.
Six young adults, 3 males, 3 females wake up in a rigged warehouse. They believe thy are on TV, part of a reality TV show that they had previously auditioned. They had given interviews about their worse fear and now they must face and conquer their fear...or die. The film initially follows a "Saw" plot, but then deviates. Meanwhile 2 detectives, with really bad lines, use their CSI skills to locate the warehouse location.
The film quickly becomes boring. It would have been better if they did copy "Saw" more.
If you like the reality show/warehouse aspect of the film, with things a little lighter, try "The Task" which I enjoyed.
