Saw was brutally simple, spending much of its runtime in a small room with two men chained to opposite walls with a corpse between them. A saw, and a way out: Cut off your foot if you want to live. The villain was a moralist, punishing his victims for perceived faults. The brilliant premise kept the budget down and begged viewers to consider if they’d cut off their own foot to survive. The next six installments in the franchise invested their substantially larger budgets (from $1,200,000 for Saw steadily increasing to an estimated $20,000,000 for Saw 3D) in inventing more creative kills. They were fun as far as the gore could carry, but didn’t always make sense. It hurt their box office take enough that after seven years of Halloween releases, viewers had to wait seven years between 2010’s Saw 3D and this year’s Jigsaw.
