Geeky Randy's summary

Rating: 5/10 (5 November 2010)

Third installment, easily inferior to the first two, is a massacre--literally and metaphorically. John Kramer (Bell), now on his death bed, is having second thoughts about his apprentice Amanda (Smith). Despite his pain and weakness, he still has one more test to give as Jigsaw. If you look closely, you know this isn't the last installment. One of the film's biggest weaknesses is that the story arcs as if it's concluding, a completely unnecessary action since just by watching the film you know it's not "the final chapter". Bahar Soomekh wins the title for the worst acting of the series. The film can sort of be commended as one of the most ruthless of the franchise, but still weak in comparison to some of the films that followed and definitely the ones the preceded.
** (out of four)
