Saw VI is not as elaborately plotted as prior sequels, but it doesn't need to be. After the last couple of halfassed tries, it's nice to have one that finally delivers a decent ending.

As usual, what gives the film whatever interest it has -- beyond satisfying the rapacious appetites of gore aficionados -- is the moral element attached to the various Rube Goldberg-style set pieces.

Because Saw does nothing to alter the look, tone, and engineered gimmickry from one movie to the next, it keeps going deeper into backstory and character arcs than horror series past, as if this ugly, cheap-looking schlock were somehow The Lord Of The Rings.

...a film so frighteningly familiar it could well be called Saw It Already.

Whereas the Friday the 13th films went off the rails with increasing inanity, at least its later episodes took some risks (however moronic) with character and formula.

...the quality of the torture machines and the importance of the rules that the subjects of the torture "games" must follow continue to decline. The Saw films have always been more about the gruesome toys and the puzzles than about the scares. In VI, one test involves dodging hot steam. That's quite a comedown from the good old days of being drowned in liquefied hog carcasses, or having to remove your own foot with a hacksaw.
