Despite Some Deep Flaws, this Film is generally solid, although fans might be heavily split(no pun intended).

Rating: Null/10 (2 November 2006)

** out of ****
I went to see this one opening day on the 26th or whatever, and i have to say that i got pretty much what i was expecting. Gore. Now don't get me wrong. I was pretty much positive that this film wasn't gonna scare me, despite high theatrics, good plot, and a generally dark tone. Well, it had all that, but the main attraction here is the violence.
The plot consists of a low level nurse being forced to try to keep Jigsaw alive for as long as another man can pass tests in some other rooms in the area whilst Jigsaw is dying of cancer. In case you haven't seen the first two films, i'll fill you in. The Jigsaw killer's hook is that he never really kills anybody but rather gets people to kill them out of their own foolishness. This film has a nasty, awkward, weird vibe to start with in the first few minutes when people are stuck in traps that are pretty much impossible to survive no matter how hard they try or no matter how smart they are.
This film is really strange because the first two films were pretty much puzzle films. Many people probably liked the first two films because of the puzzling aspects of those films. But unfortunately for sAW3(at least until the end, where the twists occur) there really aren't any aspects of the film that really make you think about the situations.
What replaces it are some truly painful and disturbing scenes of torture and gore that become nearly unwatchable for the faint-hearted. This film is a true gore-fest in the latest tradition, and while I'm glad that they totally topped HOSTAL in that area, I'm hesitant to recommend this film. But if you are a fan of gore, which many who saw the first two films were, boy oh boy are you in for a treat!!! This film is probably the goriest film so far this year. For example, there's a device called "The Rack" in which a man has his head, arms, and legs all plastered up to a big machine. And every once in a while, the spokes twist and twist his arms and legs and neck with it. Needless to say, there is a lot of snapping bones and compound fracture complete with overdone sound effects and gore. In another awesome scene, a woman has her entire ribcage torn out while attached to a metal apparatus.
So yeah, generally i'd say if you love gore, check it out, if you're looking for a good puzzle film, try to sit through it till the end. If you have a strong stomach and are looking for something scary for Halloween, check it out. Although certainly not as scary or intense as THE DEPARTED, it has a couple edge of your seat moments that should get you good. Check it out.
Rated R for strong grisly violence and gore, sequences of terror and torture, nudity and language.
