Critical response
Saw VI was not screened in advance for critics. On the review aggregator website Rotten Tomatoes, 39% of 74 critics' reviews are positive, with an average rating of 4.6/10. The website's consensus reads: "It won't earn the franchise many new fans, but Saw VI is a surprising step up for what has become an intricately grisly annual tradition." Metacritic, which uses a weighted average, assigned the film a score of 30 out of 100, based on 12 critics, indicating "generally unfavorable" reviews. Audiences polled by CinemaScore reported that the average grade moviegoers gave the film was a "B" on an A+ to F scale.
Owen Gleiberman, writing for Entertainment Weekly, said that "Saw VI is the thinnest, draggiest, and most tediously preachy of the Saw films. It's the first one that's more or less consumed by backstory—which is to say, it's one of those hollow franchise placeholders in which far too many fragments from the previous sequels keep popping up in flashbacks." He said, "If your goal is to do a quick study for a round of Saw Trivial Pursuit, then this may be the movie for you. If you're looking to be jolted into fear or queasy laughter, skip this sequel and hope that the producers get their sick act together next time." Rob Nelson of Variety wrote, "Squeezing another pint of blood from its torture porn corpus, Lionsgate slays again with Saw VI, a film so frighteningly familiar it could well be called 'Saw It Already'. At least the requisite moralism is more playful than pious in this edition", but added, "Presumably owing to director Kevin Greutert's work as editor of all five previous Saw pics, the film's juggling of chronology is the franchise's best...." IGN's Christopher Monfette rated Saw VI three out of five and wrote, "while Saw VI certainly offers a redemption for the series and the promise of a coming power struggle for Jigsaw's legacy, Saw VII will no doubt mark the time to either shake things up or watch this franchise get the ax".
Frank Scheck of The Hollywood Reporter' said, "If this is torture porn, it's as if it was designed to be enjoyed by Michael Moore." He closed his review saying, "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. Here, it's exemplified by a well-staged sequence in which a man must choose who lives or dies during a particularly lethal variation of musical chairs." Roger Moore writing for Orlando Sentinel gave the film two out of five stars. He said the script "has a more lyrical bent, and a more satiric bite, than any of the other Saw sequels" and called the acting "perfunctory on most fronts". The Los Angeles Times's Robert Abele gave the film a negative review, writing "But, really, do reformers and victims of callous health insurers really want a guy with a penchant for elaborately constructed death panels of his own to be their advocate? Elsewhere, the usual critiques apply: terrible acting, zero suspense, laughable logic and the promise of another one next year. How can we get this policy canceled?" Chris Hewitt of the St. Paul Pioneer Press gave the film a negative review. He was displeased that the film offered nothing new saying, "The first three Saw movies had some intriguing ideas and an unusual way of presenting them, but the three most recent films have barely bothered to come up with anything fresh." Kim Newman of Empire gave the film three out of five, stating "Saw VI gets back to Saw basics in gripping, gruesome manner."
Wesley Morris of The Boston Globe gave the film a two and half out of four stars saying, "Who knew that the franchise's creators would eventually find a plot twist that made sense? Who knew they'd realize that Tobin Bell's righteous killer had current-events value? Given our cable-news climate, it's not beyond imagining that John Kramer could have his own populist TV show: 'Jigsaw's Death Panel'?". Brad Miska of Bloody Disgusting gave the film seven out of ten and wrote "Saw VI is faithful to the franchise and the twist/finale are 100% satisfying. Saw fans will walk out of the theater with their fists in the air with the feeling that they've reclaimed their beloved franchise." Marc Savlov of The Austin Chronicle gave the film one and half out of five stars, saying "Enshrouding the whole gooey mess in the already blood-spattered surgical garb of the ongoing health care debate is a crafty move on the screenwriters' part, but once you get past that pseudo-ironic touch, this Saw is no more or less disturbing than any other in the series".
