Even death itself can't bring the savage games of Jigsaw to an end; as Saw IV proves; if anything; the fiendishly clever serial killer (once again played by Tobin Bell) is equally capable of dealing out violent death while lying on a morgue slab as he was in life. Saw IV also offers a class reunion of characters from the previous three films; each once again up to their necks in Jigsaw's schemes. Chief among them is Sgt. Rigg (Lyriq Bent) from Saw II; who must place himself in Jigsaw's shoes in order to rescue Detective Matthews (Donnie Walhberg); who was abducted by the killer at the end of Saw II; and Forensic Hoffman (Costas Mandylor from Saw III); from another elaborate murder device. Meanwhile; FBI agents led by Scott Patterson (Gilmore Girls; Aliens in America) attempt to track Rigg as he carries out Jigsaw's horrific notion of justice from beyond the grave. Casual horror fans may find the endless puzzles and relentless nihilism of the Saw series wearing thin with this fourth entry; but the franchise's key selling points--the Sadean excesses of Jigsaw's macabre creations--remain as bloody and unsettling as ever. --Paul Gaita
