The eighth installment in the Saw franchise features a few clever traps, but it also has sadly thin characters and ridiculous twists. (It also represents a broken promise, as the previous Saw movie, Saw 3D, said it would be the "final chapter.") The "games" in Jigsaw have the feel of a spooky, grown-up haunted house, even if the characters who are put through them are aggravatingly shallow and spend most of the movie screaming at one another.

This time, most of the movie is focused on the detectives and the medical examiners. Bonneville, it turns out, is a secret, closet Jigsaw fan who keeps a studio full of sinister sculptures. Meanwhile, her work partner, Nelson, is said to have been tortured in the war. But even this stuff doesn't really add up to much. The movie's weird final "twist" is one of those things that elicits a "huh?" response and doesn't make enough sense to warrant a second viewing. Weirdly, Jigsaw was directed by talented Australian twins Michael and Peter Spierig, whose Daybreakers and Predestination were quite good. Hopefully it was a nice paycheck for them. At least Bell, returning as Jigsaw, is fun in his few scenes on-screen.
