Behind the incessant gore and outrageous shock value of Saw, there lies a great idea for a movie. The conception of Saw, a grisly and jolting horror film of superior intelligence and primal energy, is evidence of the filmmakers' startling understanding of fear. First time director James Wan and star/writer Leigh Whannell are master thrill makers because, like the calculating killer of their movie, they consider every step that Saw may take and tunes it to scare its audience as quickly and as powerfully as possible. Unfortunately, Wan and Whannell overlooked a few inherent problems when actually creating Saw , which leaves the overall execution of their film as a mere shadow of its concept's potential.

this movie shows us how human race is stupid and selfish
