Even though Jigsaw - aka John Kramer (Tobin Bell) - is well and truly dead (the film opens with his gruesome autopsy), his 'games' continue, thanks to a message on a wax-covered microcassette found in his stomach.
Obsessed SWAT officer Daniel Rigg (Lyriq Bent) is led around the city through a series of challenges that he believes will help finally free long-missing cop Eric Matthews (Donnie Wahlberg) and Rigg's friend, detective Mark Hoffman (Costas Manylor). If he can reach them in time.
Meanwhile, FBI agents Peter Strahm (Scott Patterson) and Lindsey Perez (Athena Karkanis) believe Jigsaw had a third accomplice, as well as Amanda Young, and that's driving their investigations.
This leads them to Kramer's ex-wife, Jill Tuck (Betsy Russell) and, through a series of flashbacks, we learn a major chunk of Jigsaw's "origin story", his motivation, and get to witness his first "game"... which turned out to be less than successful.
There is a twist in the third act (isn't there always), but in the process the plot gets twisted beyond breaking point, with the story ultimately feeling like an abandoned William Burroughs cut-up experiment as it mucks around with non-sequential storytelling techniques.
Saw IV does tie in with the previous episodes in the franchise, interlocking its various puzzle pieces with the narratives of episodes one through three, but I'm still not convinced it isn't without plot holes.
There are definitely elements of later events hinging on fortuitous outcomes in earlier traps that could never have been predicted so far ahead of time.
However, among the things I have grown to appreciate about the Saw franchise, well the few opening salvos, at least, is (a) Jigsaw's code of conduct (he is testing people, and he wants them to save themselves) and (b) given Jigsaw's failing health, his ability to attract followers to his growing "cult".
Unfortunately, as the series has gone on, and its become clear that people other than Kramer are rigging his traps, innocent people are starting to suffer as collateral damage.
Because his acolytes don't adhere to his rigid guidelines, those moments of random violence simply for shits and giggles - as I said before - are when the franchise lurches over the line from horror-thriller to torture porn.
There's a danger these are becoming more in style of Eli Roth's Hostel flicks, simply challenging the endurance of the audience, and running the risk of drowning out the "learn to appreciate your life" message with buckets of fake blood.
The interesting part of this entry in the on-going saga of Jigsaw was the development of Kramer's backstory, what pushed a decent man to become a Riddler/Joker-level trap-builder and torturer.
This is the last entry in the series to be directed by Darren Lynn Bousman, until Spiral: From The Book of Saw.
However, the scriptwriters of Saw IV, Patrick Melton & Marcus Dunstan, also penned the following three chapters (Saw V, Saw VI, and Saw 3D) - which were all directed by Kevin Greutert - so it'll be interesting to see what kind of continuity there is through these latter entries in the story of Jigsaw.
As a brief aside, given their simple sequential sequel titles, I feel the film makers missed a trick with Saw IV by not having some play on "i.v." as in an intravenous drip. But maybe that's just me.
