Despite its high placement on this list, Saw IV is a pretty solid entry into the scare-filled saga, even if it's the first that starts to delve a bit too far into the "universe" of Saw, including Jigsaw's ex-wife, the extensive roster of law enforcement, and of course, cameos from previous Saw victims. Despite occasionally placing hats upon hats upon hats, this Wan-produced flick is bolstered by various memorable traps (courtesy of new franchise writers Patrick Melton and Marcus Dunstan) and confident direction from Darren Lynn Bousman, his final Saw until returning to the franchise with Spiral.
