In this once-final Saw chapter, Jigsaw helps a man loose his lust for vengeance after his son is killed by a drunk driver, while a dying John Kramer has his apprentice, Amanda Young, kidnap a doctor in order to keep him alive long enough to see his latest task through to the end. Aided by yet another strong supporting turn from Tobin Bell, who has always been good in this series even when the movies aren’t, Saw III feels much more purposeful and thoughtful than the other Saw sequels, allowing itself to find its proper sense of closure and eventually produce arguably the best (or, at least, second best) ending in the series. Alas, it was not meant to be the end. Nevertheless, Saw III stands out as the strongest, most satisfying Saw sequel to date.
